    With the coming shortage of fossil fuels and rising concerns about the environment, it is important to develop new technologies that reduce both energy consumption and pollution at the same time. In the transportation sector, new combustion processes are under development to provide clean diesel combustion with no particulate and NOx emissions. However, these processes have issues such as limited power output, high levels of unburned hydrocarbons, and carbon monoxide emissions. The aim of this paper is to determine in-cylinder flow characteristics to improve combustion performance. Combustion modeling was performed using the ECFM-3Z combustion model and 1D dynamic model and calculations on the configuration of a direct injection diesel engine were made. This study showed that the new ECFM-3Z combustion model provides results in accordance with previous research but that further studies are needed to determine the optimum engine parameters.

    There are a number of tools available for organizations wishing to measure and subsequently develop Continuous Improvement (CI). In this article, we review and evaluate a well-accepted CI development model, namely the CI Maturity Model (Bessant and Caffyn, 1997), against data collected from the 2nd...... Continuous Improvement Network Survey and a number of empirical cases described in the literature. While the CI Maturity Model suggests that CI maturation ought to be a linear process, the findings in this article suggest that there are feasible alternatives for companies to develop CI capability....

    Highlights: • Lower heating values of neat biodiesel and its blends were measured experimentally. • Lower heating value prediction models were developed based on the density and viscosity values of the fuel. • The predication models were validated by measured values and previous models. • The prediction models were used to predict the lower heating value of 24 biodiesel feedstock types produced globally. • The effects of lower heating vale on brake specific fuel consumption and thermal efficiency were investigated. - Abstract: The heating value of fuel is one of its most important physical properties, and is used for the design and numerical simulation of combustion processes within internal combustion (IC) engines. Recently, there has been a significant increase in the use of dual fuel and blended fuels in compression ignition (CI) engines. Most of the blended fuels include biodiesel as one of the constituents and hence the objective of this study is to investigate the effect of biodiesel content to lower heating value (LHV) and to develop new LHV prediction models that correlate the LHV with biodiesel fraction, density and viscosity. Furthermore, this study also investigated the effects of the LHV on CI engines performance parameters experimentally. To achieve the above mentioned objectives density, viscosity and LHV of rapeseed oil biodiesel, corn oil biodiesel and waste oil biodiesel at different blend fraction values (B0, B5, B10, B20, B50, B75, and B100, where ‘B5’ denotes a blend of 5% biodiesel and 95% mineral diesel, etc.) were measured as per EN ISO 3675:1998, EN ISO 3104:1996 and DIN 51900 standards. The engine experimental work was conducted on a four-cylinder, four-stroke, direct injection (DI) and turbocharged diesel engine by using rapeseed oil and normal diesel blends. Based on the experimental results, models were developed which have the capability to predict the LHV corresponding to different fractions, densities and viscosities of

  8. Modeling Solute Thermokinetics in LiCI-KCI Molten Salt for Nuclear Waste Separation

    Energy Technology Data Exchange (ETDEWEB)

    Morgan, Dane; Eapen, Jacob

    2013-10-01

    Recovery of actinides is an integral part of a closed nuclear fuel cycle. Pyrometallurgical nuclear fuel recycling processes have been developed in the past for recovering actinides from spent metallic and nitride fuels. The process is essentially to dissolve the spent fuel in a molten salt and then extract just the actinides for reuse in a reactor. Extraction is typically done through electrorefining, which involves electrochemical reduction of the dissolved actinides and plating onto a cathode. Knowledge of a number of basic thermokinetic properties of salts and salt-fuel mixtures is necessary for optimizing present and developing new approaches for pyrometallurgical waste processing. The properties of salt-fuel mixtures are presently being studied, but there are so many solutes and varying concentrations that direct experimental investigation is prohibitively time consuming and expensive (particularly for radioactive elements like Pu). Therefore, there is a need to reduce the number of required experiments through modeling of salt and salt-fuel mixture properties. This project will develop first-principles-based molecular modeling and simulation approaches to predict fundamental thermokinetic properties of dissolved actinides and fission products in molten salts. The focus of the proposed work is on property changes with higher concentrations (up to 5 mol%) of dissolved fuel components, where there is still very limited experimental data. The properties predicted with the modeling will be density, which is used to assess the amount of dissolved material in the salt; diffusion coefficients, which can control rates of material transport during separation; and solute activity, which determines total solubility and reduction potentials used during electrorefining. The work will focus on La, Sr, and U, which are chosen to include the important distinct categories of lanthanides, alkali earths, and actinides, respectively. Studies will be performed using LiCl-KCl salt

    Full Text Available Growing urbanisation, its related environmental impacts, and social inequalities in cities are challenges requiring a holistic urban planning perspective that takes into account the different aspects of sustainable development. One crucial point is to reconcile urban planning with environmental targets, which include decreasing energy demand and CO2 emissions, and increasing the share of renewable energy. Within this context, the project CI-NERGY aims to develop urban energy modelling, simulation and optimisation methods and tools to support decision making in urban planning. However, there are several barriers to the implementation of such tools, such as: fragmentation of involved disciplines, different stakeholders, multiplicity of scales in a city and extreme heterogeneity of data regarding all the processes to be addressed. Project CI-NERGY aims, among other goals, at overcoming these barriers, and focuses on two case study cities, Geneva in Switzerland and Vienna in Austria. In particular, project CI-NERGY faces several challenges starting with different cities, heterogeneous data sources and simulation tools, diverse user groups and their individual needs. This paper describes the experiences gathered during the project. After giving a brief overview of the project, the two case study cities, Geneva and Vienna, are briefly presented, and the focus shifts then on overall system architecture of the project, ranging from urban data modelling topics to the implementation of a Service-Oriented Architecture. Some of the challenges faced, the solutions found, as well some plans for future improvements are described and commented.

  10. Prediction models for density and viscosity of biodiesel and their effects on fuel supply system in CI engines

    Biodiesel is a promising non-toxic and biodegradable alternative fuel used in the transport sector. Nevertheless, the higher viscosity and density of biodiesel poses some acute problems when it is used it in unmodified engine. Taking this into consideration, this study has been focused towards two objectives. The first objective is to identify the effect of temperature on density and viscosity for a variety of biodiesels and also to develop a correlation between density and viscosity for these biodiesels. The second objective is to investigate and quantify the effects of density and viscosity of the biodiesels and their blends on various components of the engine fuel supply system such as fuel pump, fuel filters and fuel injector. To achieve first objective density and viscosity of rapeseed oil biodiesel, corn oil biodiesel and waste oil biodiesel blends (0B, 5B, 10B, 20B, 50B, 75B, and 100B) were tested at different temperatures using EN ISO 3675:1998 and EN ISO 3104:1996 standards. For both density and viscosity new correlations were developed and compared with published literature. A new correlation between biodiesel density and biodiesel viscosity was also developed. The second objective was achieved by using analytical models showing the effects of density and viscosity on the performance of fuel supply system. These effects were quantified over a wide range of engine operating conditions. It can be seen that the higher density and viscosity of biodiesel have a significant impact on the performance of fuel pumps and fuel filters as well as on air-fuel mixing behaviour of compression ignition (CI) engine.

    A comprehensive model has been established for calculating thermodynamic properties of multicomponent aqueous systems containing the Na{sup +}, K{sup +}, Mg{sup 2+}, Ca{sup 2+}, Cl{sup -}, and NO{sub 3}{sup -} ions. The thermodynamic framework is based on a previously developed model for mixed-solvent electrolyte solutions. The framework has been designed to reproduce the properties of salt solutions at temperatures ranging from the freezing point to 300 C and concentrations ranging from infinite dilution to the fused salt limit. The model has been parameterized using a combination of an extensive literature database and new isopiestic measurements for thirteen salt mixtures at 140 C. The measurements have been performed using Oak Ridge National Laboratory's (ORNL) previously designed gravimetric isopiestic apparatus, which makes it possible to detect solid phase precipitation. Water activities are reported for mixtures with a fixed ratio of salts as a function of the total apparent salt mole fraction. The isopiestic measurements reported here simultaneously reflect two fundamental properties of the system, i.e., the activity of water as a function of solution concentration and the occurrence of solid-liquid transitions. The thermodynamic model accurately reproduces the new isopiestic data as well as literature data for binary, ternary and higher-order subsystems. Because of its high accuracy in calculating vapor-liquid and solid-liquid equilibria, the model is suitable for studying deliquescence behavior of multicomponent salt systems.

    Full Text Available The discriminant analysis is not the inferential statistics since there are no equations for standard error (SE of error rate and discriminant coefficient based on the normal distribution. In this paper, we proposed the “k-fold cross validation for small sample” and can obtain the 95% confidence interval (CI of error rates and discriminant coefficients. This method is the computer-intensive approach by statistical and mathematical programming (MP software such as JMP and LINGO. By the proposed approach, we can choose the best model with the minimum mean of error rate in the validation samples (Minimum M2 Standard. In this research, we examine the sixteen linear separable models of Swiss banknote data by eight linear discriminant functions (LDFs. M2 of the best model of Revised IP-OLDF is the smallest value of all models. We find all coefficients of six Revised IP-OLDF among sixteen models rejected by the 95% CI of discriminant coefficients (Discriminant coefficient standard. We compare t-values of the discriminant scores. The t-value of the best model has the maximum values among sixteen models (Maximum t-value Standard. Moreover, we can conclude that all standards support the best model of Revised IP-OLDF.

  18. A Lagrangian model of air-mass photochemistry and mixing using a trajectory ensemble: the Cambridge Tropospheric Trajectory model of Chemistry And Transport (CiTTyCAT version 4.2

    Directory of Open Access Journals (Sweden)

    T. A. M. Pugh

    2012-01-01

    Full Text Available A Lagrangian model of photochemistry and mixing is described (CiTTyCAT, stemming from the Cambridge Tropospheric Trajectory model of Chemistry And Transport, which is suitable for transport and chemistry studies throughout the troposphere. Over the last five years, the model has been developed in parallel at several different institutions and here those developments have been incorporated into one "community" model and documented for the first time. The key photochemical developments include a new scheme for biogenic volatile organic compounds and updated emissions schemes. The key physical development is to evolve composition following an ensemble of trajectories within neighbouring air-masses, including a simple scheme for mixing between them via an evolving "background profile", both within the boundary layer and free troposphere. The model runs along trajectories pre-calculated using winds and temperature from meteorological analyses. In addition, boundary layer height and precipitation rates, output from the analysis model, are interpolated to trajectory points and used as inputs to the mixing and wet deposition schemes. The model is most suitable in regimes when the effects of small-scale turbulent mixing are slow relative to advection by the resolved winds so that coherent air-masses form with distinct composition and strong gradients between them. Such air-masses can persist for many days while stretching, folding and thinning. Lagrangian models offer a useful framework for picking apart the processes of air-mass evolution over inter-continental distances, without being hindered by the numerical diffusion inherent to global Eulerian models. The model, including different box and trajectory modes, is described and some output for each of the modes is presented for evaluation. The model is available for download from a Subversion-controlled repository by contacting the corresponding authors.

    The Venting and Exhausting of Low Level Air Contaminants in the Rapid Pneumatic Transport of Radioactive Samples (VELoCiRaPTORS) system is constructed to transport radioactive materials quickly and safely at the NIF. A radioactive sample will be placed inside a carrier that is transported via an airflow system produced by controlled differential pressure. Midway through the transportation process, the carrier will be stopped and vented by a powered exhaust blower which will remove radioactive gases within the transport carrier. A Geiger counter will monitor the activity of the exhaust gas to ensure that it is below acceptable levels. If the radiation level is sufficient, the carrier will pass through the remainder of the system, pneumatically braking at the counting station. The complete design will run manually or automatically with control software. Tests were performed using an inactive carrier to determine possible transportation problems. The system underwent many consecutive trials without failure. VELoCiRaPTORS is a prototype of a system that could be installed at both the Laboratory for Laser Energetics at the University of Rochester and the National Ignition Facility at LLNL.

    Full Text Available In this work, a design equation was presented for a batch-recirculated photoreactor composed of a packed bed reactor (PBR with immobilised TiO2-P25 nanoparticle thin films on glass beads, and a continuous-flow stirred tank (CFST. The photoreactor was studied in order to remove C.I. Acid Orange 7 (AO7, a monoazo anionic dye from textile industry, by means of UV/TiO2 process. The effect of different operational parameters such as the initial concentration of contaminant, the volume of solution in CFST, the volumetric flow rate of liquid, and the power of light source in the removal efficiency were examined. A rate equation for the removal of AO7 is obtained by mathematical kinetic modelling. The results of reaction kinetic analysis indicate the conformity of removal kinetics with Langmuir-Hinshelwood model (kL-H = 0.74 mg L-1 min-1, Kads = 0.081 mg-1 L. The represented design equation obtained from mathematical kinetic modelling can properly predict the removal rate constant of the contaminant under different operational conditions (R2 = 0.963. Thus the calculated and experimental results are in good agreement with each other.

    Full Text Available Nudności są nieprzyjemnym, niebolesnym odczuciem silnej, nieodpartej potrzeby zwymiotowania, z kolei wymioty polegają na gwałtownym wydaleniu treści żołądka przez usta w wyniku silnych skurczów mięśni brzucha i klatki piersiowej. Nudności i wymioty mogą występować niezależnie od siebie, ale najczęściej są ze sobą powiązane. Nudności i wymioty powstają w odpowiedzi zarówno na bodźce fizjologiczne, jak i patologiczne. Zwykle jednak przewlekłe nudności i wymioty są objawem chorób przewodu pokarmowego lub innych narządów. Choroby przewodu pokarmowego i otrzewnej stanowią szeroką grupę chorób wywołujących nudności i wymioty, począwszy od nieżytu żołądkowo-jelitowego o ostrym infekcyjnym tle, przez zatrucie pokarmowe i nadwrażliwość pokarmową, do stanów ostrych – niedrożności jelita cienkiego lub/i grubego. Leki i toksyny, między innymi cytostatyki, są jedną z najczęstszych przyczyn nudności i wymiotów. Wśród innych przyczyn nudności i wymiotów można wymienić: choroby OUN prowadzące do zwiększenia ciśnienia śródczaszkowego, choroby endokrynologiczne i metaboliczne (mocznica, kwasica ketonowa w cukrzycy, choroby tarczycy i przytarczyc oraz choroba Addisona, zawał ściany dolnej mięśnia sercowego, nudności i wymioty pooperacyjne. Nudności i wymioty jako choroby czynnościowe zostały ujęte w III kryteriach rzymskich w punkcie „Choroby czynnościowe żołądka i dwunastnicy”. W diagnostyce różnicowej należy uwzględnić czas trwania wymiotów, czas pomiędzy posiłkiem a wystąpieniem wymiotów, a także charakter treści wymiocin i inne objawy towarzyszące. Wywiad i badanie fizykalne dostarczają zwykle wystarczających informacji do postawienia prawidłowej diagnozy i ustalenia leczenia u większości chorych cierpiących na nudności i wymioty. Niektórzy pacjenci wymagają jednak badań laboratoryjnych, obrazowych i endoskopowych przed zastosowaniem odpowiedniej

    Full Text Available The article presents the first Russian translation of "Essay on Ci" with detailed comments. It was written by the outstanding Chinese poetess Li Qingzhao and considered to be the first theoretical treatise dedicated to genre ci. The article revealed that the poetess used three strategies to make a genre demarcation: to legitimise, dichotomise and historicise. To legitimise means to justify that ci is a genre of poetry by identifying the same traits with official poetry shi (e.g. using the classical quotations and allusions. To dichotomise is to determine a core element of genre and oppose it to the other element identifying the similar genre (e.g. music separates ci from shi. To historicise is to develop or discover the unique historical past (e.g. the source of ci is in antiquity. The article also examined the strategy to invent classics: Li Qingzhao wrote the apophatic history of genre ci pointing not to the merits but weaknesses of her predecessors.

    Application of fully automated systems for truck dispatching plays a major role in decreasing the transportation costs which often represent the majority of costs spent on open pit mining. Consequently, the application of a truck dispatching system has become fundamentally important in most of the world's open pit mines. Recent experiences indicate that by decreasing a truck's travelling time and the associated waiting time of its associated shovel then due to the application of a truck dispatching system the rate of production will be considerably improved. Computer-based truck dispatching systems using algorithms, advanced and accurate software are examples of these innovations. Developing an algorithm of a computer- based program appropriated to a specific mine's conditions is considered as one of the most important activities in connection with computer-based dispatching in open pit mines. In this paper the changing trend of programming and dispatching control algorithms and automation conditions will be discussed. Furthermore, since the transportation fleet of most mines use trucks with different capacities, innovative methods, operational optimisation techniques and the best possible methods for developing the required algorithm for real-time dispatching are selected by conducting research on mathematical-based planning methods. Finally, a real-time dispatching model compatible with the requirement of trucks with different capacities is developed by using two techniques of flow networks and integer programming.

    2016-01-01

    Static Code Analysis is a simple but efficient way to ensure that application’s source code is free from known flaws and security vulnerabilities. Although such analysis tools are often coming with more advanced code editors, there are a lot of people who prefer less complicated environments. The easiest solution would involve education – where to get and how to use the aforementioned tools. However, counting on the manual usage of such tools still does not guarantee their actual usage. On the other hand, reducing the required effort, according to the idea “setup once, use anytime without sweat” seems like a more promising approach. In this paper, the approach to automate code scanning, within the existing CERN’s Gitlab installation, is described. For realization of that project, the Gitlab-CI service (the “CI” stands for "Continuous Integration"), with Docker assistance, was employed to provide a variety of static code analysers for different programming languages.

    Identification of rock mass properties in terms of Rock Quality Designation (RQD) plays a significant role in mine planning and design. This study aims to separate the rock mass characterisation based on RQD data analysed from 48 boreholes in Kahang Cu-Mo porphyry deposit situated in the central Iran utilising RQD-Volume (RQD-V) and RQD-Number (RQD-N) fractal models. The log-log plots for RQD-V and RQD-N models show four rock mass populations defined by RQD thresholds of 3.55, 25.12 and 89.12% and 10.47, 41.68 and 83.17% respectively which represent very poor, poor, good and excellent rocks based on Deere and Miller rock classification. The RQD-V and RQD-N models indicate that the excellent rocks are situated in the NW and central parts of this deposit however, the good rocks are located in the most parts of the deposit. The results of validation of the fractal models with the RQD block model show that the RQD-N fractal model of excellent rock quality is better than the RQD-V fractal model of the same rock quality. Correlation between results of the fractal and the geological models illustrates that the excellent rocks are associated with porphyric quartz diorite (PQD) units. The results reveal that there is a multifractal nature in rock characterisation with respect to RQD for the Kahang deposit. The proposed fractal model can be intended for the better understanding of the rock quality for purpose of determination of the final pit slope.

    Full Text Available Według pierwszych wytycznych dotyczących postępowania w astmie leczenie astmy zależy od stopnia jej cięż- kości, określonej na podstawie objawów klinicznych i wskaźników czynności płuc. Ponieważ astma jest chorobą o zmiennym przebiegu, duże znaczenie ma jej ciągła ocena kliniczna i dostosowana do niej modyfikacja leczenia. Niestety, stopień ciężkości nie dopasowuje się elastycznie do odpowiedzi na leczenie. Biorąc ten fakt pod uwagę, światowi eksperci zalecają zmianę w postępowaniu z astmą, przedkładając uzyskanie klinicznej kontroli astmy nad ustaleniem stopnia jej ciężkości, wyróżniając astmę kontrolowaną, częściowo kontrolowaną i niekontrolowaną. Uzyskanie stanu pełnej kontroli astmy formułuje się w raporcie GINA 2006 jako główny cel leczenia. Kontrola astmy odnosi się do stopnia opanowania objawów i byłoby najlepiej, gdyby dotyczyła też markerów zapalenia i patofizjologicznych wykładników choroby. Określenie stopnia kontroli choroby zgodnie z obecnymi założeniami stanowi podstawę wyboru i modyfikacji leczenia – właściwe ustalenie stopnia kontroli astmy wpływa na skuteczność leczenia. Obecnie dostępnych jest wiele metod oceny kontroli astmy, wtym ocena parametrów klinicznych (objawy w ciągu dnia, objawy nocne, stosowanie leków rozszerzających oskrzela, ocena czynności płuc (PEF i FEV1, określenie zaawansowania zapalenia w drogach oddechowych (nieswoista nadreaktywność oskrzeli, stężenie tlenku azotu w powietrzu wydechowym, liczba eozynofili w plwocinie indukowanej.

    Highlights: • Physical and chemical characterization of biodiesel particulates. • Toxicity of biodiesel particulate due to EC/OC, PAHs and BTEX. • Trace metals and unregulated emissions from biodiesel fuelled diesel engines. • Influence of aftertreatment devices and injection strategy on biodiesel particulates. • Characterization of biodiesel particulate size-number distribution. - Abstract: Compression ignition (CI) engines are the most popular prime-movers for transportation sector as well as for stationary applications. Petroleum reserves are rapidly and continuously depleting at an alarming pace and there is an urgent need to find alternative energy resources to control both, the global warming and the air pollution, which is primarily attributed to combustion of fossil fuels. In last couple of decades, biodiesel has emerged as the most important alternative fuel candidate to mineral diesel. Numerous experimental investigations have confirmed that biodiesel results in improved engine performance, lower emissions, particularly lower particulate mass emissions vis-à-vis mineral diesel and is therefore relatively more environment friendly fuel, being renewable in nature. Environmental and health effects of particulates are not simply dependent on the particulate mass emissions but these change depending upon varying physical and chemical characteristics of particulates. Particulate characteristics are dependent on largely unpredictable interactions between engine technology, after-treatment technology, engine operating conditions as well as fuel and lubricating oil properties. This review paper presents an exhaustive summary of literature on the effect of biodiesel and its blends on exhaust particulate’s physical characteristics (such as particulate mass, particle number-size distribution, particle surface area-size distribution, surface morphology) and chemical characteristics (such as elemental and organic carbon content, speciation of polyaromatic

    A new configuration-driven CI algorithm is outlined which eliminates the need for explicit comparison of pairs of Slater determinants through the use of a series of compact tables. In this scheme each pair of configurations is either shown to be non-interacting or to fall into one of nine cases, each of which is characterized fully once certain orbital permutations are determined. The program is divided into three parts: a case structure analysis step including integral label generation, a sort of the required electron repulsion integrals, and finally a procedure in which the foregoing information is combined with tabulated directions for the evaluation of the necessary Hamiltonian matrix elements over spin-adapted functions. Timing improvements of up to more than a factor of four have been achieved with the new algorithm

    There is a lack of recommended models for clinical informatics (CI) governance that can facilitate successful health information technology implementation. To understand existing CI governance structures and provide a model with recommended roles, partnerships, and councils based on perspectives of nursing informatics leaders. We conducted a cross-sectional study through administering a survey via telephone to facilitate semistructured interviews from June 2012 through November 2012. We interviewed 12 nursing informatics leaders, across the United States, currently serving in executive- or director-level CI roles at integrated health care systems that have pioneered electronic health records implementation projects. We found the following 4 themes emerge: (1) Interprofessional partnerships are essential. (2) Critical role-based levels of practice and competencies need to be defined. (3) Integration into existing clinical infrastructure facilitates success. (4) CI governance is an evolving process. We described specific lessons learned and a model of CI governance with recommended roles, partnerships, and councils from the perspective of nursing informatics leaders. Applied CI work is highly interprofessional with patient safety implications that heighten the need for best practice models for governance structures, adequate resource allocation, and role-based competencies. Overall, there is a notable lack of a centralized CI group comprised of formally trained informaticians to provide expertise and promote adherence to informatics principles within EHR implementation governance structures. Our model of the nursing domain of CI governance with recommended roles, partnerships, and councils provides a starting point that should be further explored and validated. Not only can the model be used to understand, shape, and standardize roles, competencies, and structures within CI practice for nursing, it can be used within other clinical domains and by other informaticians

    We present the detection of neutral atomic carbon CI(3P1-3P0) line emission towards omi Cet. This is the first time that CI is detected in the envelope around an oxygen-rich M-type asymptotic giant branch (AGB) star. We also confirm the previously tentative CI detection around V Hya, a carbon-rich AGB star. As one of the main photodissociation products of parent species in the circumstellar envelope (CSE) around evolved stars, CI can be used to trace sources of ultraviolet (UV) radiation in CSEs. The observed flux density towards omi Cet can be reproduced by a shell with a peak atomic fractional abundance of 2.4 × 10-5 predicted based on a simple chemical model where CO is dissociated by the interstellar radiation field. However, the CI emission is shifted by 4 km s-1 from the stellar velocity. Based on this velocity shift, we suggest that the detected CI emission towards omi Cet potentially arises from a compact region near its hot binary companion. The velocity shift could, therefore, be the result of the orbital velocity of the binary companion around omi Cet. In this case, the CI column density is estimated to be 1.1 × 1019 cm-2. This would imply that strong UV radiation from the companion and/or accretion of matter between two stars is most likely the origin of the CI enhancement. However, this hypothesis can be confirmed by high-angular resolution observations.

    Full Text Available The purpose of this paper is to offer a logico‑philosophical critical overview of the theory of multiple realities (TWR. The paper is divided into three sections. In the first section I present a brief history of the development of some ideas, which combined together form the conceptual framework of the theory in question, whose main thesis is that there is more than one reality. In the second part I present (and try to address some interpretations of TWR, which can be described as: ontological; epistemological; esthetical; logical ad mixed interpretations. When doing so, a special emphasis is laid on the presentation of an explication of TWR based on theory of models, an explication authored by Teresa Kostyrko. This explication rests on a conditional recognition of the particular ‘realities’ of Chwistek’s theory as proper models (i.e. those, which fulfill the condition of the identity of meaning of theory’s fundamental notions of the theories of reality, with the provision that such models are indeed constructible. In the last section of my paper I propose a preliminary appraisal of the TWR as well as a way to reengineer this theory in order to avoid some of its difficulties. By appealing to Kostyrko’s idea on one hand and the spirit Quinean ontological relativism on the other, I wish to argue as follows: (1 ‘reality’ is the name of the set comprising all meanings of the term ‘reality’; (2 under particular conditions these meanings can be arranged in a theory, which possesses a proper model (scientific discourse, some forms of the common talk; (3 model proper designate by definition classes of objects, which we regard as existent on the grounds of a given theory. The above set of theses forms the core of a concept, which I propose to call the ‘manifold reality’ in order to differentiate it from TWR, the development of which theory it is, as well as its modification towards a new kind of ontology.

    The main objective of this study was to assess the associations between self-reported listening habits and perception of music and speech perception outcomes in quiet and noise for both unilateral cochlear implant (CI) users and bimodal (CI in one ear, hearing aid in contra-lateral ear) users. Information concerning music appreciation was gathered by means of a newly developed questionnaire. Moreover, audiological data (pure-tone audiometry, speech tests in noise and quiet) were gathered and the relationship between speech perception and music appreciation is studied. Bimodal users enjoy listening to music more in comparison with unilateral CI users. Also, music training within rehabilitation is still uncommon, while CI recipients believe that music training might be helpful to maximize their potential with current CI technology. Music training should not be exclusively reserved for the good speech performers. Therefore, a music training program (MTP) that consists of different difficulty levels should be developed. Hopefully, early implementation of MTP in rehabilitation programs can enable adult CI users to enjoy and appreciate music and to maximize their potential with commercially available technology. Furthermore, because bimodal users consider the bimodal stimulation to be the most enjoyable way to listen to music, CI users with residual hearing in the contra-lateral ear should be encouraged to continue wearing their hearing aid in that ear.

    Existing reflectance spectra of CI chondrites (18 spectra of 3 CIs) have been augmented with new (18 spectra of 2 CIs) reflectance spectra to ascertain the spectral variability of this meteorite class and provide insights into their spectral properties as a function of grain size, composition, particle packing, and viewing geometry. Particle packing and viewing geometry effects have not previously been examined for CI chondrites. The current analysis is focused on the 0.3-2.5 μm interval, as this region is available for the largest number of CI spectra. Reflectance spectra of powdered CI1 chondrites are uniformly dark (IOM), as no other CI opaque phase appears able to produce concurrent darkening and bluing. Magnetite can also explain the presence of an absorption feature near 1 μm in some CI spectra. The most blue-sloped spectra are generally associated with the larger grain size samples. For incidence and emission angles <60°, increasing phase angle results in darker and redder spectra, particularly below ∼1 μm. At high incidence angles (60°), increasing emission angle results in brighter and redder spectra. More densely packed samples and underdense (fluffed) samples show lower overall reflectance than normally packed and flat-surface powdered samples. Some B-class asteroids exhibit selected spectral properties consistent with CI chondrites, although perfect spectral matches have not been found. Because many CI chondrite spectra exhibit absorption features that can be related to specific mineral phases, the search for CI parent bodies can fruitfully be conducted using such parameters.

  19. A modified CAS-CI approach for an efficient calculation of magnetic exchange coupling constants

    Fink, Karin; Staemmler, Volker

    2013-09-01

    A modification of the conventional wavefunction-based CAS-CI method for the calculation of magnetic exchange coupling constants J in small molecules and transition metal complexes is presented. In general, CAS-CI approaches yield much too small values for J since the energies of the important charge transfer configurations are calculated with the ground state orbitals and are therefore much too high. In the present approach we improve these energies by accounting for the relaxation of the orbitals in the charge transfer configurations. The necessary relaxation energies R can be obtained in separate calculations using mononuclear or binuclear model systems. The method is applied to a few examples, small molecules, binuclear transition metal complexes, and bulk NiO. It allows to obtaining fairly reliable estimates for J at costs that are not higher than those of conventional CAS-CI calculations. Therefore, extended and very time-consuming perturbation theory (PT2), configuration interaction (CI), or coupled cluster (CC) schemes on top of the CAS-CI calculation can be avoided and the modified CAS-CI (MCAS-CI) approach can be applied to rather large systems.

Wyznaczono częstość i prawdopodobieństwo wystąpienia ciśnienia o oddziaływaniu bodźcowym oraz zanalizowano zależność zmian międzydobowych ciśnienia od typów cyrkulacji atmosferycznej według klasyfikacji Lityńskiego. Do obliczeń wykorzystano cogodzinne wartości ciśnienia atmosferycznego pochodzące ze stacji Ursynów SGGW z okresu 2011–2015. Na podstawie badań stwierdzono, że ciśnienie atmosferyczne o oddziaływaniu bodźcowym w Warszawie może wystąpić w każdym miesiącu z prawdopodobieństwem od 0,2% do 19,1%, w przypadku ciśnienia o wartościach wyższych niż 1015 hPa oraz od 0,1 do 3,4%, w przypadku ciśnienia niższego od 985 hPa, z wyjątkiem czerwca i sierpnia. Zmiany międzydobowe ciśnienia atmosferycznego mogą osiągać około 24 hPa, a częstość występowania bodźców „silnych” wywołanych tymi zmianami wyniosła w poszczególnych miesiącach od 1% do 16%, natomiast bodźców „bardzo silnych” od 2% do 8%. Spośród sytuacji synoptycznych największe znaczenie dla bodźcowości zmian ciśnienia mają sytuacje cyklonalne: szczególnie przy adwekcji powietrza z sektora północno-zachodniego (NWC.

  1. Implications of CI therapy for Visual Deficit Training

    Full Text Available We address here the question of whether the techniques of CI therapy, a family of treatments that has been employed in the rehabilitation of movement and language after brain damage might apply to the rehabilitation of such visual deficits as unilateral spatial neglect and visual field deficits. CI therapy has been used successfully for the upper and lower extremities after chronic stroke, cerebral palsy (CP, multiple sclerosis (MS, other CNS degenerative conditions, resection of motor areas of the brain, focal hand dystonia, and aphasia. Treatments making use of similar methods have proven efficacious for amblyopia.The CI therapy approach consists of four major components: intensive training, training by shaping, a transfer package to facilitate the transfer of gains from the treatment setting to everyday activities, and strong discouragement of compensatory strategies.CI therapy is said to be effective because it overcomes learned nonuse, a learned inhibition of movement that follows injury to the CNS. In addition, CI therapy produces substantial increases in the grey matter of motor areas on both sides of the brain. We propose here that these mechanisms are examples of more general processes: learned nonuse being considered parallel to sensory nonuse following damage to sensory areas of the brain, with both having in common diminished neural connections (DNC in the nervous system as an underlying mechanism. CI therapy would achieve its therapeutic effect by strengthening the diminished neural connections. Use-dependent cortical reorganization is considered to be an example of the more general neuroplastic mechanism of brain structure repurposing (BSR. If the mechanisms involved in these broader categories are involved in each of the deficits being considered, then it may be the principles underlying efficacious treatment in each case may be similar. The lessons learned during CI therapy research might then prove useful for the treatment of

    Businesses use the Internet as a way to communicate company information as a way of engaging their customers. As the use of the Web for business transactions and advertising grows, so too, does the amount of useful information for practitioners of competitive intelligence (CI). CI is the legal and ethical practice of information gathering about competitors and the marketplace. Information sources like company webpages, online newspapers and news organizations, electronic journal articles and reports, and Internet search engines allow CI practitioners analyze company strengths and weaknesses for their customers. More company and marketplace information than ever is available on the Internet and a lot of it is free. Companies should view the Web not only as a business tool but also as a source of competitive intelligence. In a highly competitive marketplace can any organization afford to ignore information about the other players and customers in that same marketplace?

No início do século XX, a ciência modifica o real percebido através das lentes dos microscópios e das teorias da física moderna; o parentesco entre cinema e ciência está principalmente naquilo que excede o campo perceptivo e é explorado neste artigo para mostrar como a tensão entre o caráter estático da fotografia e a fluidez fugitiva do tempo revela a ciência sem seus estereótipos habituais.

    Objectives The purpose of the study was to evaluate content coverage and data quality of the Clinical Data Dictionary (CiDD) developed by the Center for Interoperable EHR (CiEHR). Methods A total of 12,994 terms were collected from 98 clinical forms of a tertiary cancer center hospital with 500 beds. After data cleaning, 9,418 terms were mapped with the data items of the CiDD by the research team, and validated by 30 doctors and nurses at the research hospital. Results Mapping results were classified into five categories: lexically mapped; semantically mapped; mapped to either a broader term or a narrower term; mapped to more than one term and not mapped. In terms of coverage, out of 9,418 terms, 6,750 (71.7%) terms were mapped; 4,319 (45.9%) terms were lexically mapped; 2,431 (25.8%) were semantically mapped; 281 (3.0%) terms were mapped to a broader term; 43 (0.5%) were mapped to a narrower term; and 550 (5.8%) were mapped to more than one term. In terms of data quality, the CiDD has problems such as errors in concept namingand representation, redundancy in synonyms, inadequate synonyms, and ambiguity in meaning. Conclusions Although the CiDD has terms covering 72% of local clinical terms, the CiDD can be improved by cleaning up errors and redundancies, adding textual definitions or use cases of the concept, and arranging the concepts in a hierarchy.

    Wright, Rose; Uchanski, Rosalie M.

    2012-01-01

    Background The inability to hear music well may contribute to decreased quality of life for cochlear implant (CI) users. Researchers have reported recently on the generally poor ability of CI users’ to perceive music, and a few researchers have reported on the enjoyment of music by CI users. However, the relation between music perception skills and music enjoyment is much less explored. Only one study has attempted to predict CI users’ enjoyment and perception of music from the users’ demographic variables and other perceptual skills (Gfeller et al., 2008). Gfeller’s results yielded different predictive relationships for music perception and music enjoyment, and the relationships were weak, at best. Purpose The first goal of this study is to clarify the nature and relationship between music perception skills and musical enjoyment for CI users, by employing a battery of music tests. The second goal is to determine whether normal hearing (NH) subjects, listening with a CI-simulation, can be used as a model to represent actual CI users for either music enjoyment ratings or music perception tasks. Research Design A prospective, cross-sectional observational study. Original music stimuli (unprocessed) were presented to CI users, and music stimuli processed with CI-simulation software were presented to twenty NH listeners (CIsim). As a control, original music stimuli were also presented to five other NH listeners. All listeners appraised twenty-four musical excerpts, performed music perception tests, and filled out a musical background questionnaire. Music perception tests were the Appreciation of Music in Cochlear Implantees (AMICI), Montreal Battery for Evaluation of Amusia (MBEA), Melodic Contour Identification (MCI), and University of Washington Clinical Assessment of Music Perception (UW-CAMP). Study Sample Twenty-five NH adults (22 – 56 years old), recruited from the local and research communities, participated in the study. Ten adult CI users (46 – 80

    Full Text Available This article aims to reflect on the possible articulations of the development of science in the education of children and their respective childhoods. While in Kindergarten and Elementary School students are, above all, children, and as such, subjects endowed with intelligence, emotions, and feelings. They are able to make observations, retain information, propose arguments, participate in discussions, and make choices that allow them to exercise free expression of theirs thoughts in many different languages. However, to ensure the effective participation of the child as a subject of today, not an intented being, it is necessary to reconsider the actions and relationships in the school environment. In this sense, this study highlights contributions on how the educational process of science can/should be thought in the process of children education. Also, we hope to provide access to scientific culture without detracting the childhoods. We highlight the possibility of using some powerful elements of science in the school environment to sharpen curiosity and improve new worldviews. Often different from the adult perspective, science in children education should emphasize issues such as the specificity of child logic, which encompasses creativity, imagination, fantasy, and desire. This article, in its theoretical nature, discusses notions such as childhood, children, and science in order to consider a type of early childhood education in which an educational routine with elements of scientific culture would enable the occurrence of childhood practice.

    Full Text Available Otyłość jest zjawiskiem coraz częściej występującym na świecie. Szacuje się, że ponad połowę dorosłej populacji krajów uprzemysłowionych dotknęła nadwaga, a odsetek otyłości w niektórych krajach (USA, Wielka Brytania wzrasta do 30%. Ta niepokojąca tendencja obserwowana jest również w populacji dzieci i młodzieży. Epidemia otyłości rozpoczęła się w latach 80. i trwa nieprzerwanie do chwili obecnej, stając się poważnym problemem społeczno-medycznym współczesnego świata. Przyczyny tego zjawiska są złożone i wynikają z uwarunkowań biologicznych i środowiskowych, w szczególności z niedostatecznej codziennej aktywności fizycznej oraz złych nawyków żywieniowych. Do tej pory nie udało się wypracować w pełni efektywnej strategii leczenia otyłości. Promocja zdrowego stylu życia oraz właściwych nawyków żywieniowych adresowana do całej populacji stanowi podstawę prewencji i leczenia otyłości. Powszechnie stosowane różnego rodzaju diety odchudzające zawierają często sprzeczne zalecenia. Istniejące kontrowersje utrudniają wybór skutecznej diety w celu redukcji masy ciała, a ich mnogość i różnorodność wprowadzają swoisty chaos informacyjny. Efekty wielu diet są krótkotrwałe i obarczone efektem jo-jo. W wielu przypadkach brak jest jakichkolwiek przesłanek naukowych uzasadniających dane postępowanie dietetyczne. Właśnie dlatego wciąż istnieje potrzeba prowadzenia dalszych badań naukowych umożliwiających w sposób obiektywny ocenę skuteczności dietetycznych metod leczenia otyłości. W niniejszej pracy autorzy przedstawiają spotykane w praktyce różne dietetyczne podejścia do problemu otyłości, wskazując na ich efektywność i naukowe uzasadnienie.

Konsekwencją nieradzenia sobie z własną seksualnością, jej odbiorem rodzinnym lub społecznym mogą być zaburzenia depresyjne, lękowe, zaburzenia odżywiania oraz różnorodne formy autoagresji. W obliczu wysokie‑ go ryzyka występowania zaburzeń psychicznych u osób w wieku rozwojowym, u których seksualność kształtuje się w sposób odmienny, należy rozważać szerokie spektrum czynników mogących determinować takie, a nie inne oblicze seksualności. Intencją autorów pracy było przedstawienie, w oparciu o przypadek kliniczny, historii człowieka odkry‑ wającego swoją tożsamość płciową, biorąc pod uwagę zarówno osobnicze uwarunkowania, przebyte zdarzenia trau‑ matyczne, jak i kontekst rodzinny pacjenta oraz konsekwencje procesu coming out. Autorzy starali się zwrócić uwagę na złożoność i wielostopniowość procesu ujawniania się, który stał się możliwy dopiero po zapewnieniu adolescen‑ towi zrozumienia, wsparcia i akceptacji. Tym samym ukazano kluczową rolę środowiska, które może sprzyjać pro‑ cesowi odkrywania się i umożliwić go lub przeciwnie – utrudnić czy też całkowicie go zablokować. Transseksualizm w różnych środowiskach budzi sporo kontrowersji, pytań i wątpliwości. Historia hospitalizowanego pacjenta obrazu‑ je złożoność problemów, z którymi zmagają się osoby z zaburzeniami tożsamości

    High activity 'point' sources of 155 Eu are used for medical and industrial applications. For this purpose we have studied a method of obtaining I Ci of carrier free 155 Eu, with a solid residue smaller than 5 mg per Ci. In order to separate the 155 Eu from several grams of a 154 Sm enriched target we propose a procedure which is based on the work of Bouissieres and David, Onstott, and Takekoshi et al. The separation is carried out by electrolysis on a mercury cathode followed by purification on ion exchange resin. The yields of the europium separation and target recovery are 80 per cent and 90 per cent respectively. The time required for the procedure is three days. (authors) [fr

    Full Text Available Atualmente, não se pode pensar no estudo do comportamento humano sem considerar a abordagem científica a este objeto: o campo da Psicologia científica. Esse campo é disputado por diversos enfoques teóricos que divergem quanto ao modo como definem ciência e comportamento humano. A abordagem de B. F. Skinner foi bastante proeminente no século XX, mas ainda continua a ser mal-entendida. Partindo do desenvolvimento histórico de sua obra, o presente texto visa a iluminar alguns aspectos relacionados às noções de ciência e comportamento humano desse autor e ressaltar as transformações por que passaram. Analisam-se três tópicos da obra de Skinner: seu período inicial (de 1930 a cerca de 1938, a obra "Ciência e Comportamento Humano" de 1953, e as influências da Biologia. São enfatizados aspectos relevantes da sua teorização sobre o tema: busca por relações funcionais, ênfase nos dados empíricos, operacionismo, externalismo, multideterminação do comportamento, experimentalismo, previsão e controle, ética.

    The comprehensive in vitro proarrhythmia assay (CiPA) is a nonclinical, mechanism-based paradigm for assessing drug proarrhythmic liability. The first CiPA assay determines effects on cloned human cardiac ion channels. The second investigates whether the latter study-generated metrics engender proarrhythmic markers on a computationally reconstructed human ventricular action potential. The third evaluates conclusions from, and searches possibly missed effects by in silico analysis, in human stem cell-derived cardiomyocytes (hSC-CMs). CiPA ad hoc Expert-Working Groups have proposed patch clamp protocols for seven cardiac ion channels, a modified O'Hara-Rudy model for in silico analysis, detailed procedures for field (MEA) and action potential (VSD) measurements in hSC-CMs, and 29 reference drugs for CiPA assay testing and validation. CiPA adoption as drug development tool for identifying electrophysiological mechanisms conferring proarrhythmic liability to candidate drugs is a complex, multi-functional task requiring significant time, reflection, and efforts to be fully achieved.

    Full Text Available Padaczka jest jedną z najczęstszych chorób ośrodkowego układu nerwowego, występującą u około 1% populacji na świecie. Charakteryzuje się występowaniem nawracających napadów o różnej symptomatologii. Szacuje się, że u 30% pacjentów mimo prowadzonego właściwego leczenia przeciwpadaczkowego nadal występują napady drgawkowe. Jest to tak zwane zjawisko lekooporności. W Polsce problem ten dotyczy około 100 000–120 000 chorych. Czynnikami predysponującymi do wystąpienia padaczki lekoopornej są: ujawnienie się choroby przed 1. rokiem życia, duża częstotliwość napadów przed rozpoczęciem leczenia oraz zmiany strukturalne mózgu, w tym wady rozwojowe kory mózgowej. Niekontrolowane napady padaczkowe pogarszają jakość życia chorych, zwiększając ryzyko urazów, wpływając negatywnie na samopoczucie fizyczne oraz funkcjonowanie psychospołeczne. Chociaż znane są potencjalne czynniki ryzyka, to nadal nie wiadomo, dlaczego u dwóch pacjentów z tym samym rodzajem padaczki lub tym samym typem napadów skuteczność leczenia lekami przeciwpadaczkowymi może być skrajnie różna. Wśród możliwych przyczyn tego zjawiska wymienia się czynniki genetyczne, zmieniające właściwości farmakodynamiczne i farmakokinetyczne stosowanych leków. Do grupy tych czynników zalicza się: genetycznie uwarunkowany polimorfizm niektórych enzymów mikrosomalnych (CYP2C9, CYP2C19, glikoproteiny P, białka MRP (multidrug resistance-associated protein oraz zaburzenia funkcji farmakodynamicznych receptorów GABA (GABAA i kana- łów jonowych.

  9. Combustion Stratification for Naphtha from CI Combustion to PPC

    KAUST Repository

    Vallinayagam, R.

    2017-03-28

    This study demonstrates the combustion stratification from conventional compression ignition (CI) combustion to partially premixed combustion (PPC). Experiments are performed in an optical CI engine at a speed of 1200 rpm for diesel and naphtha (RON = 46). The motored pressure at TDC is maintained at 35 bar and fuelMEP is kept constant at 5.1 bar to account for the difference in fuel properties between naphtha and diesel. Single injection strategy is employed and the fuel is injected at a pressure of 800 bar. Photron FASTCAM SA4 that captures in-cylinder combustion at the rate of 10000 frames per second is employed. The captured high speed video is processed to study the combustion homogeneity based on an algorithm reported in previous studies. Starting from late fuel injection timings, combustion stratification is investigated by advancing the fuel injection timings. For late start of injection (SOI), a direct link between SOI and combustion phasing is noticed. At early SOI, combustion phasing depends on both intake air temperature and SOI. In order to match the combustion phasing (CA50) of diesel, the intake air temperature is increased to 90°C for naphtha. The combustion stratification from CI to PPC is also investigated for various level of dilution by displacing oxygen with nitrogen in the intake. The start of combustion (SOC) was delayed with the increase in dilution and to compensate for this, the intake air temperature is increased. The mixture homogeneity is enhanced for higher dilution due to longer ignition delay. The results show that high speed image is initially blue and then turned yellow, indicating soot formation and oxidation. The luminosity of combustion images decreases with early SOI and increased dilution. The images are processed to generate the level of stratification based on the image intensity. The level of stratification is same for diesel and naphtha at various SOI. When O concentration in the intake is decreased to 17.7% and 14

    An analysis of ultraviolet and optical spectroscopy is presented for the symbiotic binary CI Cyg. This system contains an M5 II asymptotic branch giant Mg of about 1.5 solar mass, transfering material at a few times 0.00001 solar mass/yr into a large accretion disk surrounding a main-sequence star with Mh of about 0.5 solar mass. A boundary layer at the inner edge of the disk photoionizes a small nebula approximately confined to the Roche volume of the accreting star. An extended, more highly ionized region forms when material ejected from the disk interacts with the red giant wind. 115 refs

Foram utilizados: questionário, entrevista, produção de textos, análise documental e a técnica de grupo focal para a coleta de dados. De modo geral, os alunos possuem sentidos que reconhecem Lésbicas, Gays, Bissexuais e Transgêneros (LGBT como "estranhos", mesmo assim, acreditam que têm o dever de respeitar as escolhas de cada um. As travestis foram declaradamente apresentadas com repúdio por eles, sendo a homossexualidade e bissexualidade aparentemente mais aceitas. Os professores parecem manter aulas que não abordam estas questões, mesmo o Ensino de Ciências, sendo um momento privilegiado para problematizações sobre diversidade sexual e gênero. É necessário investir em discussões sobre esses temas na formação inicial e continuada de professores, buscando a construção de novos sentidos e práticas que se preocupem com o desvelamento de significados preconceituosos sobre gênero e diversidade sexual.

  13. The radiation shielding potential of CI and CM chondrites

    Galactic Cosmic Rays (GCRs) and Solar Energetic Particles (SEPs) pose a serious limit on the duration of deep space human missions. A shield composed of a bulk mass of material in which the incident particles deposit their energy is the simplest way to attenuate the radiation. The cost of bringing the sufficient mass from the Earth's surface is prohibitive. The shielding properties of asteroidal material, which is readily available in space, are investigated. Solution of Bethe's equation is implemented for incident protons and the application in composite materials and the significance of various correction terms are discussed; the density correction is implemented. The solution is benchmarked and shows good agreement with the results in literature which implement more correction terms within the energy ranges considered. The shielding properties of CI and CM asteroidal taxonomy groups and major asteroidal minerals are presented in terms of stopping force. The results show that CI and CM chondrites have better stopping properties than Aluminium. Beneficiation is discussed and is shown to have a significant effect on the stopping power.

    The electron spectrum of the M 2 and M 3 levels in bromine and krypton have been studied by high resolution ESCA. The M 1 Msub(2,3) super Coster-Kronig transitions become energetically forbidden for Z >approximately 36 (Kr) and recent calculations therefore predict a decrease in the M 2 and M 3 natural linewidths around krypton in the periodic system. The experiment shows that the 3psub(3/2) linewidth is smaller in Kr than in Br. It is, however, also found that this decrease in linewidth is followed by configuration interaction (CI) between 3p 2 P and 3d 2 nl * 2 P states. Several discrete CI resonances are observed in the Kr 3p spectrum. Such resonances are also studied in the N shell for the elements from Te(Z=52) to Ba(Z=56). For these elements the effect is found to be much larger due to the strong collective character of 4d-nf* excitations. (Auth.)

    Full Text Available Regularna aktywność ruchowa wywołuje szereg zmian adaptacyjnych, zwłaszcza w układzie krążenia i przemianie materii. W licznych pracach na temat pojedynczego wysiłku i wzmożonej aktywności fizycznej pojawia się coraz więcej potwierdzeń ich korzystnego wpływu na kształtowanie funkcji poznawczych. U podstaw mechanizmów związanych z tym wpływem leżą zmiany anatomiczne i funkcjonalne, m.in. zwiększenie przepływu krwi przez mózg, angiogenezy i neurogenezy, objętości istoty szarej w korze czołowej i skroniowej. Wysiłek pobudza wydzielanie czynników troficznych, wśród których dla procesów poznawczych, plastyczności synaptycznej, poprawy szlaków sygnałowych neurogenezy i funkcji naczyniowych kluczowe są czynnik troficzny pochodzenia mózgowego i insulinopodobny czynnik wzrostowy. Aktywność ruchowa wywołuje wzmożoną ekspresję czynnika troficznego pochodzenia mózgowego, co pozytywnie wpływa na procesy energetyczne i aktywuje w mózgu wiele układów energetycznych, które korzystnie modyfikują potencjał synaptyczny przetwarzania informacji ważnych w kształtowaniu funkcji poznawczych. Wysiłek redukuje stan zapalny przez obniżenie we krwi stężenia cytokin prozapalnych, mogących się przyczyniać do rozwoju procesów neurodegeneracyjnych. Redukuje czynniki ryzyka zespołu metabolicznego, a zwłaszcza nadciśnienie i insulinooporność, więc zmniejsza ryzyko wystąpienia zaburzeń czynności poznawczych, poprawia funkcjonowanie mózgu, opóźnia początek i spowalnia rozwój zaburzeń w chorobach neurodegeneracyjnych, a wśród nich w chorobie Alzheimera i chorobie Parkinsona. Za sprawą wymienionych mechanizmów aktywność ruchowa wydaje się niezbędna do zachowania prawidłowych funkcji poznawczych w każdym wieku.

    The capacity and mechanism with which nonviable Aspergillus niger removed the textile dye, C.I. Direct Blue 199, from aqueous solution was investigated using different parameters, such as initial dye concentration, pH and temperature. In batch experiments, the biosorption capacity increased with decrease in pH, and the maximum dye uptake capacity of the biosorbent was 29.96 mg g{sup -1} at 400 mg L{sup -1} dye concentration and 45 deg. C. The Langmuir and Freundlich models were able to describe the biosorption equilibrium of C.I. Direct Blue 199 onto the fungal biomass. Biosorption followed a pseudo-second order kinetic model with high correlation coefficients (r{sup 2} > 0.99). Thermodynamic studies revealed that the biosorption process was successful, spontaneous and endothermic in nature.

    Full Text Available Fish diets were analyzed to evaluate the dynamic trophs of the fish community in the Churince wetland system of the Cuatro Ciénegas, where the fauna consists of nine species: endemic, native and introduced. In nine sampling events (between February 2011 and May 2014 556 specimens of all nine species were collected. Stomach contents were analyzed and the Relative Importance Index (IRI was calculated. The feed coefficient (Q of the diets and the accumulated trophic diversity (Hk, as well as the amplitude of the trophic niche were evaluated. Feeding strategies in the fish community were found to be eurifagic. The main foods in general were insects, crustaceans, gastropods, plants and teleosts. According to the average linkage method, four functional trophic groups were defined, with no higher consumption species; nevertheless all were regulators, mainly invertebrates. Therefore, the chain reaction in food control was higher from top to bottom, meaning a downwards dietary control.

    The present study intends to explore the in-cylinder combustion and evolution of soot emission during the transition from conventional compression ignition (CI) combustion to partially premixed combustion (PPC) at low load conditions. In-cylinder combustion images and engine-out emissions were measured in an optical engine fueled with low octane heavy naphtha fuel (RON = 50). Full cycle engine simulations were performed using a three-dimensional computational fluid dynamics code CONVERGETM, coupled with gas phase chemical kinetics, turbulence, and particulate size mimic soot model. The simulations were performed under low load conditions (IMEP ~ 2 to 3 bar) at an engine speed of 1200 rpm. The start of injection (SOI) was advanced from late (-10 CAD aTDC) to early fuel injection timings (-40 CAD aTDC) to realize the combustion transition from CI combustion to PPC. The simulation results of combustion and emission are compared with the experimental results at both CI and PPC combustion modes. The results of the study show a typical low-temperature stratified lean combustion at PPC mode, while high-temperature spray-driven combustion is evident at CI mode. The in-cylinder small intermediates species such as acetylene (C2H2), propargyl (C3H3), cyclopentadienyl (C5H5) and polycyclic aromatic hydrocarbons (PAHs) were significantly suppressed at PPC mode. Nucleation reaction of PAHs collision contributed to main soot mass production. The distribution of soot mass and particle number density was consistent with the distribution of high-temperature zones at CI and PPC combustion modes.

    We present the results from an observing campaign on the star CI Cam carried out at the IOTA interferometer in November-December 2004 using the IONIC 3 telescope beam combiner in the H spectral band with projected baselines in the range 10-36m. CI Cam is a known B[e] star and X-ray transient source and has been intensively observed since its powerful X-ray, radio and optical outburst occurred in April 1998. Our visibility measurements put strong constraints on the nature of the source and we can rule out all existing SED models available in the literature. Our new results are in agreement with previous observations of CI Cam obtained with IOTA2 in the H and K' spectral bands in September-November 1998, indicating the infrared excess is long-lived and not directly associated with the outburst. We have explored new models that can better fit our observations. Additionally, we have measured small non-zero closure phases which are the signature of asymmetries in the brightness distribution function.

In this work, the concentration and distribution of the major and minor components of pharmaceutical tablets are determined and the spatial distribution from the internal and external sides has been obtained. In addition, the same NIR-CI allowed the coating thickness and its surface distribution to be quantified. Images were processed to extract the target data and calibration models constructed using the Partial Least Squares (PLS algorithms. The concentrations of Active Pharmaceutical Ingredient (API and excipients obtained for uncoated cores were essentially identical to the nominal values of the pharmaceutical formulation.

    Glutamate decarboxylase (GAD), as a key enzyme in the γ -aminobutyric acid (GABA) shunt, catalyzes the decarboxylation of L-glutamate to form GABA. This pathway has attracted much interest because of its roles in carbon and nitrogen metabolism, stress responses, and signaling in higher plants. The aim of this study was to isolate and characterize genes encoding GADs from Caragana intermedia , an important nitrogen-fixing leguminous shrub. Two full-length cDNAs encoding GADs (designated as CiGAD1 and CiGAD2 ) were isolated and characterized. Multiple alignment and phylogenetic analyses were conducted to evaluate their structures and identities to each other and to homologs in other plants. Tissue expression analyses were conducted to evaluate their transcriptional responses to stress (NaCl, ZnSO 4 , CdCl 2 , high/low temperature, and dehydration) and exogenous abscisic acid. The CiGAD s contained the conserved PLP domain and calmodulin (CaM)-binding domain in the C-terminal region. The phylogenetic analysis showed that they were more closely related to the GADs of soybean, another legume, than to GADs of other model plants. According to Southern blotting analysis, CiGAD1 had one copy and CiGAD2 -related genes were present as two copies in C. intermedia . In the tissue expression analyses, there were much higher transcript levels of CiGAD2 than CiGAD1 in bark, suggesting that CiGAD2 might play a role in secondary growth of woody plants. Several stress treatments (NaCl, ZnSO 4 , CdCl 2 , high/low temperature, and dehydration) significantly increased the transcript levels of both CiGAD s, except for CiGAD2 under Cd stress. The CiGAD1 transcript levels strongly increased in response to Zn stress (74.3-fold increase in roots) and heat stress (218.1-fold increase in leaves). The transcript levels of both CiGAD s significantly increased as GABA accumulated during a 24-h salt treatment. Abscisic acid was involved in regulating the expression of these two CiGAD s under salt

  14. Experimental and Numerical Investigation of Ethanol/Diethyl Ether Mixtures in a CI Engine

    The auto-ignition characteristics of diethyl ether (DEE)/ethanol mixtures are investigated in compression ignition (CI) engines both numerically and experimentally. While DEE has a higher derived cetane number (DCN) of 139, ethanol exhibits poor ignition characteristics with a DCN of 8. DEE was used as an ignition promoter for the operation of ethanol in a CI engine. Mixtures of DEE and ethanol (DE), i.e., DE75 (75% DEE + 25% ethanol), DE50 (50% DEE + 50% ethanol) and DE25 (25% DEE + 75% ethanol), were tested in a CI engine. While DE75 and DE50 auto-ignited at an inlet air pressure of 1.5 bar, DE25 failed to auto-ignite even at boosted pressure of 2 bar. The peak in-cylinder pressure for diesel and DE75 were comparable, while DE50 showed reduced peak in-cylinder pressure with delayed start of combustion (SOC). Numerical simulations were conducted to study the engine combustion characteristics of DE mixture. A comprehensive detailed chemical kinetic model was created to represent the combustion of DE mixtures. The detailed mechanism was then reduced using standard direct relation graph (DRG-X) method and coupled with 3D CFD code, CONVERGE, to simulate the experimental data. The simulation results showed that the effects of physical properties on DE50 combustion are negligible. Simulations of DE50 mixture revealed that the combustion is nearly homogenous, while diesel (n-heptane used as a surrogate) and DE75 showed similar combustion behavior with flame liftoff and diffusion controlled combustion. Diesel exhibited auto-ignition at an equivalence ratio of 2, while DE75 and DE50 showed auto-ignition in the equivalence ratio range of 1-1.5 and 0-1, respectively. The experiments and numerical simulations demonstrate how the high reactivity of DEE supports the auto-ignition of ethanol, while ethanol acts as a radical scavenger.

    Assay performance is dependent on the accuracy and precision of a given method. These attributes can be combined into an analytical Sigma-metric, providing a simple value for laboratorians to use in evaluating a test method's capability to meet its analytical quality requirements. Sigma-metrics were determined for 37 clinical chemistry assays, 13 immunoassays, and 3 ICT methods on the Alinity ci system. Analytical Performance Specifications were defined for the assays, following a rationale of using CLIA goals first, then Ricos Desirable goals when CLIA did not regulate the method, and then other sources if the Ricos Desirable goal was unrealistic. A precision study was conducted at Abbott on each assay using the Alinity ci system following the CLSI EP05-A2 protocol. Bias was estimated following the CLSI EP09-A3 protocol using samples with concentrations spanning the assay's measuring interval tested in duplicate on the Alinity ci system and ARCHITECT c8000 and i2000 SR systems, where testing was also performed at Abbott. Using the regression model, the %bias was estimated at an important medical decisions point. Then the Sigma-metric was estimated for each assay and was plotted on a method decision chart. The Sigma-metric was calculated using the equation: Sigma-metric=(%TEa-|%bias|)/%CV. The Sigma-metrics and Normalized Method Decision charts demonstrate that a majority of the Alinity assays perform at least at five Sigma or higher, at or near critical medical decision levels. More than 90% of the assays performed at Five and Six Sigma. None performed below Three Sigma. Sigma-metrics plotted on Normalized Method Decision charts provide useful evaluations of performance. The majority of Alinity ci system assays had sigma values >5 and thus laboratories can expect excellent or world class performance. Laboratorians can use these tools as aids in choosing high-quality products, further contributing to the delivery of excellent quality healthcare for patients

  19. Fluctuations of Wigner-type random matrices associated with symmetric spaces of class DIII and CI

    2018-02-01

    Wigner-type randomizations of the tangent spaces of classical symmetric spaces can be thought of as ordinary Wigner matrices on which additional symmetries have been imposed. In particular, they fall within the scope of a framework, due to Schenker and Schulz-Baldes, for the study of fluctuations of Wigner matrices with additional dependencies among their entries. In this contribution, we complement the results of these authors by explicit calculations of the asymptotic covariances for symmetry classes DIII and CI and thus obtain explicit CLTs for these classes. On the technical level, the present work is an exercise in controlling the cumulative effect of systematically occurring sign factors in an involved sum of products by setting up a suitable combinatorial model for the summands. This aspect may be of independent interest. Research supported by Deutsche Forschungsgemeinschaft (DFG) via SFB 878.

    The effect of the kappa-opioid receptor agonist enadoline (CI977, (5R)-(5 alpha,7 alpha,8 beta)-N-methyl-N-[7-(1-pyrrilidinyl)-1-oxaspiro [4,5]dec-8-yl-4-benzofuranacetamide monohydrochloride), on the release of amino acids was studied in the hippocampus of freely moving rats. K+, 100 mM, or veratrine, 100 microM, were applied for 10 min via the dialysis probe, either alone (control groups) or together with CI977 (after a 10 min pretreatment with CI977 in the perfusion medium). To test the specificity of the response to CI977, nor-binaltorphimine, a selective kappa-opioid receptor antagonist, was delivered together with CI977 in two groups of animals. To test the effect of systemic injection, CI977 was given subcutaneously 30 min prior to either stimulus. K(+)-induced release of glutamate and aspartate was significantly reduced by CI977, 2.5 mM; release of gamma-aminobutyric acid (GABA) was reduced by 250 microM CI977 in the probe. The effect of CI977 on release of glutamate and aspartate, but not of GABA, was reversed by nor-binaltorphimine (45 microM). Systemic treatment with CI977, 1 or 10 mg/kg, did not reduce K(+)-induced release of glutamate. Veratrine-induced release of aspartate and glutamate was significantly inhibited by 25 microM and release of GABA by 250 microM CI977 in the probe, and this effect was not modified by nor-binaltorphimine (58 microM). Systemic injection of CI977 1 mg/kg significantly reduced veratrine-induced release of glutamate. These results indicate that CI977 regulates release of amino acids by two independent mechanisms.(ABSTRACT TRUNCATED AT 250 WORDS)

    We search for signatures of a distant planet around the two million-year-old classical T-Tauri star CI Tau hosting a hot-Jupiter candidate ({M}{{p}}\\sin i∼ 8.1 {M}Jupiter}) in an eccentric orbit (e ∼ 0.3). To probe the existence of an outer perturber, we reanalyzed 1.3 mm dust continuum observations of the protoplanetary disk around CI Tau obtained by the Atacama Large Millimeter/submillimeter Array (ALMA). We found a gap structure at ∼0.″8 in CI Tau’s disk. Our visibility fitting assuming an axisymmetric surface brightness profile suggested that the gap is located at a deprojected radius of 104.5 ± 1.6 au and has a width of 36.9 ± 2.9 au. The brightness temperature around the gap was calculated to be ∼2.3 K lower than that of the ambient disk. Gap-opening mechanisms such as secular gravitational instability (GI) and dust trapping can explain the gap morphology in the CI Tau disk. The scenario that an unseen planet created the observed gap structure cannot be ruled out, although the coexistence of an eccentric hot Jupiter and a distant planet around the young CI Tau would be challenging for gravitational scattering scenarios. The mass of the planet was estimated to be between ∼0.25 M Jupiter and ∼0.8 M Jupiter from the gap width and depth ({0.41}-0.06+0.04) in the modeled surface brightness image, which is lower than the current detection limits of high-contrast direct imaging. The young classical T-Tauri CI Tau may be a unique system for exploring the existence of a potential distant planet as well as the origin of an eccentric hot Jupiter.

  5. Application of the graphical unitary group approach to the energy second derivative for CI wave functions via the coupled perturbed CI equations

    International Nuclear Information System (INIS)

    Fox, D.J.

    1983-10-01

    Analytic derivatives of the potential energy for Self-Consistent-Field (SCF) wave functions have been developed in recent years and found to be useful tools. The first derivative for configuration interaction (CI) wave functions is also available. This work details the extension of analytic methods to energy second derivatives for CI wave functions. The principal extension required for second derivatives is evaluation of the first order change in the CI wave function with respect to a nuclear perturbation. The shape driven graphical unitary group approach (SDGUGA) direct CI program was adapted to evaluate this term via the coupled-perturbed CI equations. Several iterative schemes are compared for use in solving these equations. The pilot program makes no use of molecular symmetry but the timing results show that utilization of molecular symmetry is desirable. The principles for defining and solving a set of symmetry adapted equations are discussed. Evaluation of the second derivative also requires the solution of the second order coupled-perturbed Hartree-Fock equations to obtain the correction to the molecular orbitals due to the nuclear perturbation. This process takes a consistently higher percentage of the computation time than for the first order equations alone and a strategy for its reduction is discussed

    Radioiodine therapy is the safest, simplest, least expensive and most effective method for treatment in most patients with Graves' disease. Due to complexity of methods for dose determination, the tendency is toward using fixed doses of I-131 for this purpose. As there is conflict for the best fixed dose, regarding it's efficiency and complication of hypothyroidism, standardized dose selection is of particular importance in treatment of Grave' disease. 59 patients with grave' disease, referred to the nuclear medicine center of Shariati Hospital from 78.5.25 were studied. In this clinical trial, the patients were randomized into two groups, one were treated with 5 mCi of 1-131 and the other received 10 mCi of the same agent. All patients were followed for two years, with 6-month intervals. Among 65 patients treated with I-131, 20 (33 9%) patients became euthyroid and 19(32.2%) became hypothyroid while relapse was noticed in 20 patients (33.9%) In The group treated by 5 mCi I-131 (33 patients), 10(30%) were euthyroid, 6(18.2%) were hypothyroid (overall cure of 48.5% while 17(51.5%) remained hyperthyroid by the end of the follow -up period(two years). From the 26 patients who were treated with 10 mCi, the euthyroid, hypothyroid and hypothyroid states were observed in 10(38.5%), 13(50%), 13(50%) and 3(11.5%) patients respectively (with an overall cure rate of 88.5%). No relationship was noted between the outcome and age, sex, size of the thyroid gland and thyroid uptake, but the relationship between the disease outcome and the amount of administered radioiodine was statistically significant (P=0.003). For most of the patients, age, sex, iodine uptake and even thyroid size play minor roles in dose selection. Although the incidence-rate of early hypothyroidism (by the end of 2 years) in the cases related with 5 mCi is less than those treated with 10 mCi, the incidence of relapse is greatly higher in the former group. In addition, it was found that long

  15. Effect of Inhomogeneous Mixture Properties on CI Combustion in a Schnurle-Type Gasoline DI Engine

    Science.gov (United States)

    Kim, Seok-Woo; Moriyoshi, Yasuo

    The authors have performed experiments on compression-ignition (CI) for a single-cylinder Schnurle-type two-stroke gasoline direct injection (DI) engine which employs a variable exhaust port, area, and deduced two presumptions from the experimental results. Firstly, the spatial distributions of fuel concentration and in-cylinder gas temperature are indispensable to enable CI operation under stratified charge conditions, because CI operation is not possible in a DI system although the necessary conditions of the scavenging efficiency and the in-cylinder gas temperature for the initiation of CI in homogeneous charge conditions are satisfied. Secondly, it is possible that flame propagation occurs in stratified charge CI conditions, because the combustion period in the later stage after 80% mass burned becomes longer than that with homogeneous charge CI combustion. In this report, in order to verify the above two presumptions deduced from experiments, the gas exchange process and mixture formation process were numerically analyzed, and the initiation conditions of CI were estimated using a CHEMKIN application. As a result, in case of CI with a late injection timing in DI system, it was found that CI was possible because high temperature but no fuel region and low temperature but rich fuel region exist in the cylinder due to inhomogeneous spatial distributions of fuel and temperature. Also, in case of CI with a late injection timing, the flame propagation was possible in the low-temperature and diluted rich region. Thereby, the two presumptions deduced from the experimental results were validated from the numerical analysis results.

  16. Life and death of an influential passenger: Wolbachia and the evolution of CI-modifiers by their hosts.

    Directory of Open Access Journals (Sweden)

    Arnulf Koehncke

    Full Text Available Wolbachia are intracellular bacteria widely distributed among arthropods and nematodes. In many insect species these bacteria induce a cytoplasmic incompatibility (CI between sperm of infected males and eggs of uninfected females. From an evolutionary point of view, CI is puzzling: In order to induce this modification-rescue system, Wolbachia affect sperm of infected males even though Wolbachia are only transmitted maternally. Phylogenetic studies of Wolbachia and hosts show that the bacteria rarely cospeciate with their hosts, indicating that infections are lost in host species. However, the mechanisms leading to Wolbachia loss are not well understood.Using a population genetic model, we investigate the spread of host mutants that enhance or repress Wolbachia action by affecting either bacterial transmission or the level of CI. We show that host mutants that decrease CI-levels in males (e.g. by reducing Wolbachia-density during spermatogenesis spread, even at cost to mutant males. Increase of these mutants can lead to loss of Wolbachia infections, either as a direct consequence of their increase or in a step-wise manner, and we derive analytically a threshold penetrance above which a mutation's spread leads to extinction of Wolbachia. Selection on host modifiers is sexually antagonistic in that, conversely, host mutants that enhance Wolbachia in females are favoured whereas suppressors are not.Our results indicate that Wolbachia is likely to be lost from host populations on long evolutionary time scales due to reduction of CI levels in males. This can occur either by evolution of single host modifiers with large effects or through accumulation of several modifier alleles with small effects on Wolbachia action, even at cost to mutant males and even if infected hosts do not incur fecundity costs. This possibility is consistent with recent findings and may help to explain the apparent short evolutionary persistence times of Wolbachia in many host

  17. Complex coordinate rotation and relativistic Hylleraas-CI: helium isoelectronic series

    International Nuclear Information System (INIS)

    2007-01-01

    A combination of the Hylleraas-CI (Hy-CI) and complex coordinate rotation (CCR) methods has been applied to study the nuclear charge dependence of the eigenvalues of the Dirac-Coulomb (DC) Hamiltonian corresponding to the ground states of helium isoelectronic series atoms. It has been shown that the CCR, due to the separation of the localized states from the unphysical Brown-Ravenhall continuum, removes the instabilities of the bound-state eigenvalues observed in large-basis set Hy-CI results. The Hy-CI-CCR results are in very good agreement with the most accurate ones available in the literature. Surprisingly, the difference between the DC Hy-CI-CCR eigenvalues and the eigenvalues of the positive-energy projected no-pair Hamiltonian is equal, up to the numerical accuracy of the results, to (Zα) 3 /6π, i.e. to (Zα) 3 relativistic many-body perturbation theory contribution for electron-electron Coulomb interaction operator. An excellent agreement between the Hy-CI-CCR eigenvalues shifted by (Zα) 3 /6π and the no-pair ones confirms the very high accuracy achieved in both approaches. The numerical accuracy of the Hy-CI-CCR DC eigenvalues is estimated to eight significant figures

    Serum albumin-toxic dye interaction studies will be of paramount importance in the field of toxicology due to its relation towards the distribution and transportation of dye in blood. In this regard, the binding between C.I. Acid Red 88 (AR88) and serum albumins (HSA and BSA) was investigated by using combination of spectroscopic and molecular modeling methods. The fluorescence results revealed that AR88 interact with serum albumins through the combination of static and dynamic quenching mechanism. The distance “r” between serum albumin and AR88 was obtained according to the Forster resonance energy transfer (FRET) theory. Synchronous fluorescence and CD spectral results showed alterations in the microenvironment and conformation of serum albumins. The molecular docking method is also employed to understand the interaction of AR88 with serum albumins. All these studies confirm that BSA has more affinity towards AR88 than that of HSA which suggests that AR88 is more easily transported in the body of bovid than human and so it is more hazardous to bovids. -- Highlights: • AR88 interacts with serum albumin through the combination of both static and dynamic quenching mechanism. • The binding site of AR88 in serum albumins is nearer to tryptophan moiety. • Circular Dichroism spectra showed that AR88 alters α-helicity of serum albumin. • This interaction study could be greatly imperative for further investigations in toxicology

  20. Capturing the Petermann Ice Island Flux With the CI2D3 Database

    The Petermann Glacier ice tongue lost >460 km2 of areal extent ( 38 Gt of mass) due to three large calving events in 2008, 2010 and 2012, as well as three previously unrecorded events in 2011 and 2012. Hundreds of ice islands subsequently drifted south between Hall Basin and Newfoundland's Grand Banks, but no systematic data collection or analysis has been conducted for the full flux of fragments prior to the present study. To accomplish this, the Canadian Ice Service's extensive RADARSAT-1 and -2 synthetic aperture radar image archive was mined to create the Canadian Ice Island Drift, Deterioration and Detection (CI2D3) Database. Over 15000 fragments have been digitized in GIS software from 3200 SAR scenes. A unique characteristic of the database is the inclusion of the lineage (i.e., connecting repeat observations or mother-daughter fragments) for all tracked fragments with areas >0.25 km2. This genealogical information was used to isolate ice islands that were about to fracture in order to assess the environmental conditions and morphological characteristics that influence this deterioration mechanism. Fracture counts showed a significant relationship with sea ice concentration (r = -0.56). However, variations in relative thickness played a large role in fracturing likelihood regardless of sea ice conditions. The exceedance probability of the daughter fragment length was calculated, as is often conducted for offshore industry hazard assessment. Grounded ice islands, which are hazards to seafloor installations and disturb benthic ecology, were recognized from their negligible drift speeds and two grounding hot-spots were identified along the Coburg and eastern Baffin island coasts. Petermann ice islands have been noted to drift along specific isobaths due to the influence of bathymetry on ocean currents. 50% of observations occurred between the 100 and 300 m isobaths, and smaller ice islands were observed more frequently in deeper regions. The CI2D3 Database can

    Nitrogen concentration in the gate oxide plays a key role for 90 nm and below ULSI technology. Techniques like secondary ionization mass spectroscopy (SIMS) and X-ray photoelectron spectroscopy (XPS) are commonly used for understanding N concentration. This paper describes the application of the carrier illuminationTM (CI) technique to measure the nitrogen concentration in ultra-thin gate oxides. A set of ultra-thin gate oxide wafers with different DPN (decoupled plasma nitridation) treatment conditions were measured using the CI technique. The CI signal has excellent correlation with the N concentration as measured by XPS

    2017-12-01

    The performance of the novel ammonium-CI3-TOF utilizing NH4+ adduct ion chemistry to measure quantitatively first generation oxidized product molecules (OMs) as well as highly oxidized organic molecules (HOMs) was investigated for the first time. The gas-phase ozonolysis of cyclohexene served as a test system in order to evaluate the capability of the detection systems. Experiments have been carried out in the TROPOS free-jet flow system at close to atmospheric conditions. Product ion signals were simultaneously observed by the ammonium-CI3-TOF and the acetate-CI-API-TOF. Both instruments are in remarkable good agreement within a factor of two for HOMs. For OMs not containing an OOH group the acetate technique can considerably underestimate OM concentrations by 2-3 orders of magnitude. First steps of cyclohexene ozonolysis generate ten different (m/z product peaks) main products comprising 92% of observed OMs. The remaining 8% are distributed over several (m/z peaks) minor products that can be attributed to HOMs, predominately to highly oxidized RO2 radicals. Summing up, observed ammonium-CI3-TOF products yield 4.9 x 109 molecules cm-³ in excellent agreement with the amount of reacted cyclohexene of 5.0 x 109 molecules cm-³ for reactant concentrations of [O3] = 2.25 x 1012 molecules cm-³ and [cyclohexene] = 2.0 x 1012 molecules cm-³ and a reaction time of 7.9 s. NH4+ adduct ion chemistry based CIMS techniques offer a unique opportunity for complete detection of the whole product distribution, and consequently, for a much better understanding of atmospheric oxidation processes.

    Sixty-seven patient with painful bone metastases were randomized to two groups. Group 1 (n=34) received 1.0 mCi/kg of 153 Sm-EDTMP and group II (n=33) received 1.5 mCi/kg. All of them met inclusion criteria and there was no significantly difference between the basic conditions of two groups. After receiving 153 Sm-EDTMP intravenously, all patients were kept in close follow-up weekly with blood counting, physician visiting and collecting patient's self-filling-in diary including pain score, Karnofsky performance scale and analgesic consumption. The follow-up duration was six weeks. The final overall condition assessed by physician were graded into no change (including worse), slight relief, significant relief and complete relief. Only significant relief and complete relief were considered as effectiveness for pain relief. Haematological toxicity grade was evaluated based on the nadir of WBC ad PLT counts. The results indicated that the higher dosage group had a higher effectiveness rate (75.76%) compared to the lower dosage group (67.65%), but without statistic significance (x 2 =0.5365, 0.25 153 Sm-EDTMP could be used for those patients with better haematological function and 1.0 mCi/kg used for those patients with poorer haematological function.

    The transcription of two Ciona intestinalis galectin genes (CiLgals-a and CiLgals-b) is uparegulated by LPS in the pharynxis (hemocytes, vessel epithelium, endostilar zones) which is retained the main organ of the immunity. In this ascidian, for the first time we show, by immunohistochemistry and in situ hybridization methods, that these two immune-related genes are expressed in the gastric epithelium of naïve ascidians, whereas the galectins appear to be only contained in the intestine columnar epithelium. In addition, according to previous results on the pharynx, the genes are also expressed and galectins produced by hemocytes scattered in the connective tissue surrounding the gut. The genes expression and galectin localization in several tissues, including the previous findings on the transcription upregulation, the constitutive expression of these genes by endostylar zones and by the gastric epithelium suggest a potential multifunctional role of these galectins. In this respect, it is of interest to define where the CiLgals are normally found as related to the tissue functions. Such an approach should be a starting point for further investigations.

    Full Text Available Procurou-se identificar as consequências mais importantes da concepção de ciência de Popper, que deu origem a um rico debate na Filosofia das Ciências, para o Ensino de Ciências. O acompanhamento deste debate permite perceber a riqueza do processo científico, reconhecendo as contribuições daqueles que debateram com Popper; bem como a importância dos aspectos da ciência que Popper valorizou e procurou preservar. As críticas e os debates em torno das abordagens de mudança conceitual contribuíram para a percepção da riqueza e complexidade desse processo. Quando considerados os objetivos institucionais das escolas e as expectativas sociais em torno da compreensão adequada e da procura de superação dos paradigmas vigentes a manutenção de certos aspectos, inerentes ao processo de mudança conceitual, pode se mostrar relevante. Neste sentido, a obra de Popper pode oferecer importante apoio para valorizar aspectos racionais que poderiam presidir o processo de aprender Ciências.This work aimed at identifying the most important consequences of Popper's conception of science education, which started a fertile debate in the Philosophy of Science. By following this debate, it is possible to notice the richness of the cientific process, recognizing the contributions brought by those who debated with Popper, and the importance of aspects of science that Popper valued and attempted to preserve. The criticism and the debate over the approaches towards conceptual change contributed to the perception of the wide extent and complexity of this process. However, the maintenance of certain aspects, inherent in the process of conceptual change, may be relevant when the institutional objectives of the schools and the social expectations over the appropriate understanding and over the attempt to overcome current paradigms are considered. In this way, Popper's work may offer important support to valuing rational aspects that could inform the process

    2015-01-01

    Constrained density functional theory with configuration interaction (CDFT-CI) is a useful, low-cost tool for the computational prediction of electronic couplings between pseudo-diabatic constrained electronic states. Such couplings are of paramount importance in electron transfer theory and transition state theory, among other areas of chemistry. Unfortunately, CDFT-CI occasionally fails significantly, predicting a coupling that does not decay exponentially with distance and/or overestimating the expected coupling by an order of magnitude or more. In this communication, we show that the eigenvalues of the difference density matrix between the two constrained states can be used as an a priori metric to determine when CDFT-CI are likely to be reliable: when the eigenvalues are near 0 or ±1, transfer of a whole electron is occurring, and CDFT-CI can be trusted. We demonstrate the utility of this metric with several illustrative examples

    Near-infrared chemical imaging (NIR-CI) is an emerging technology that combines traditional near-infrared spectroscopy with chemical imaging. Therefore, NIR-CI can extract spectral information from pharmaceutical products and simultaneously visualize the spatial distribution of chemical components. The rapid and non-destructive features of NIR-CI make it an attractive process analytical technology (PAT) for identifying and monitoring critical control parameters during the pharmaceutical manufacturing process. This review mainly focuses on the pharmaceutical applications of NIR-CI in each unit operation during the manufacturing processes, from the Western solid dosage forms to the Chinese materia medica preparations. Finally, future applications of chemical imaging in the pharmaceutical industry are discussed. Copyright © 2015 John Wiley & Sons, Ltd.

    2011-10-20

    Unrestricted Natural Orbital-Complete Active Space Configuration Interaction, abbreviated as UNO-CAS, has been implemented for NDDO-based semiempirical molecular-orbital (MO) theory. A computationally more economic technique, UNO-CIS, in which we use a configuration interaction (CI) calculation with only single excitations (CIS) to calculate excited states, has also been implemented and tested. The class of techniques in which unrestricted natural orbitals (UNOs) are used as the reference for CI calculations is denoted UNO-CI. Semiempirical UNO-CI gives good results for the optical band gaps of organic semiconductors such as polyynes and polyacenes, which are promising materials for nanoelectronics. The results of these semiempirical UNO-CI techniques are generally in better agreement with experiment than those obtained with the corresponding conventional semiempirical CI methods and comparable to or better than those obtained with far more computationally expensive methods such as time-dependent density-functional theory. We also show that symmetry breaking in semiempirical UHF calculations is very useful for predicting the diradical character of organic compounds in the singlet spin state.

    85 -801 Bydgoszcz e – mail: magdalena.sowa@cm.umk.pl         Streszczenie Wprowadzenie: Rak piersi w ciąży jest rozpoznawany stosunkowo rzadko. W ostatnich dziesięciu latach w Europie można zauważyć wyraźną tendencję do odraczania macierzyństwa wśród młodych kobiet. Obecnie średnia wieku kobiet rodzących pierwsze dziecko wynosi 30 lat. Jednym z czynników ryzyka zachorowania na raka piersi jest wiek. Z uwagi na fakt, iż kobiety coraz później decydują się na macierzyństwo, a średnia wieku występowania raka piersi się obniża,  z tą szczególną sytuacją kliniczną lekarzom jak i kobietom przyjdzie się zmagać coraz częściej.  Cel pracy:Celem pracy była próba przybliżenia odmienności procesu diagnostyki i leczenia raka gruczołu piersiowego rozpoznanego w ciąży. Rozwinięcie:Z danych epidemiologicznych wynika, iż rak piersi jest najczęściej występującym nowotworem u kobiet ciężarnych.Szczególnie niebezpiecznym jest fakt, iż zmiany fizjologicznie zachodzące w organizmie kobiety już od pierwszych tygodni ciąży, mogą maskować pojawienie się guza i znacznie opóźniać wdrożenie procesu diagnostyki.  Choroba nowotworowa rozpoznana w czasie trwania ciąży jest zawsze dramatyczną i ogromnie stresującą sytuacją dla kobiety i jej najbliższych, dlatego proces diagnostyki i leczenia jest silnie zindywidualizowany, zaś maksymalny efekt terapeutyczny z jednoczesną ochroną nienarodzonego dziecka stanowi priorytet działań. Podsumowanie:Decyzje terapeutyczne podejmowane są po uwzględnieniu ogólnego stanu zdrowia pacjentki, stopnia zaawansowania klinicznego nowotworu, wieku ciążowego oraz postulatów samej pacjentki i jej najbliższych.W niniejszej pracy, posługując się metodą analizy piśmiennictwa szczegółowo omówiono odmienności w procesie diagnostyki i leczenia raka piersi u kobiet ciężarnych.   Słowa kluczowe: rak piersi, ciąża, diagnostyka, leczenie   Breast cancer during pregnancy

    Transforming growth factor (TGF-β) is a well-known component of a regulatory cytokines superfamily that has pleiotropic functions in a broad range of cell types and is involved, in vertebrates, in numerous physiological and pathological processes. In the current study, we report on Ciona intestinalis molecular characterisation and expression of a transforming growth factor β homologue (CiTGF-β). The gene organisation, phylogenetic tree and modelling supported the close relationship with the mammalian TGF suggesting that the C. intestinalis TGF-β gene shares a common ancestor in the chordate lineages. Functionally, real-time PCR analysis showed that CiTGF-β was transcriptionally upregulated in the inflammatory process induced by LPS inoculation, suggesting that is involved in the first phase and significant in the secondary phase of the inflammatory response in which cell differentiation occurs. In situ hybridisation assays revealed that the genes transcription was upregulated in the pharynx, the main organ of the ascidian immune system, and expressed by cluster of hemocytes inside the pharynx vessels. These data supported the view that CiTGF-β is a potential molecule in immune defence systems against bacterial infection. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Stwardnienie rozsiane (łac. sclerosis multiplex, SM jest główną przyczyną niepełnosprawności u młodych dorosłych i jak większość chorób autoimmunologicznych częściej dotyczy kobiet. Wpływ ciąży na przebieg SM wzbudza zainteresowanie od wielu lat, a w ostatnim okresie stanowi temat badań wieloośrodkowych. Ciąża to zwykle okres bardzo dobrego samopoczucia chorych, najczęściej bez rzutów. Wynika to ze zmiany reaktywności immunologicznej na korzyść reakcji przeciwzapalnych związanych z limfocytami Th2 i cytokinami antyzapalnymi (interleukina 4, 5, 6, 10, TGF-β. Po porodzie zmienia się reaktywność immunologiczna i aktywność choroby wzrasta. Większość badań nie wykazała ogólnego negatywnego wpływu ciąży na niesprawność długoterminową związaną z SM; stwardnienie rozsiane nie ma negatywnego wpływu na przebieg ciąży, porodu i stan dziecka, dlatego chore kobiety mogą planować potomstwo. Choroba nie zwiększa ryzyka powikłań w ciąży i podczas porodu ani wad wrodzonych u dziecka w porównaniu z populacją ogólną. Jednakże każda terapia immunomodulująca jest przeciwwskazana w ciąży. Jeśli pacjentka decyduje się na dziecko, powinna przerwać leczenie; zaleca się również przerwę od leków przed zajściem w ciążę. W pracy podsumowano dostępne informacje na temat klinicznych problemów dotyczących ciąży i porodu u chorych na SM oraz oceniono zagrożenia dla dziecka związane z podawaniem leków.

    Full Text Available Wstęp: Somatyczne wielkości, takie jak masa (Mc i wysokość ciała (Wc, są używane do wyliczania wskaźników wagowo--wzrostowych i stanowią pomoc w diagnozowaniu nadwagi i otyłości. Cel pracy: Celem pracy jest ocena nadwagi i otyłości kobiet i mężczyzn w świetle prostych wskaźników somatycznych. Materiał i metody: W prezentowanej pracy porównano wskaźniki somatyczne 179 kobiet i 181 mężczyzn z nadwagą i otyłością. Do oceny somatycznej badanych użyto: Mc, Wc oraz wskaźników wagowo-wzrostowych: Queteleta, BMI, Rohrera i smukłości. Wyniki: W badanych grupach kobiety i mężczyźni byli w zbliżonym wieku, grupy te różniły się istotnie omawianymi wskaźnikami somatycznymi. Porównania podgrup kobiet i mężczyzn o podobnej wielkości BMI wykazały, że są oni w podobnym wieku i różnią się w zakresie Mc, Wc oraz wskaźników: Queteleta, Rohrera i smukłości. Natomiast między podgrupami kobiet, jak i między podgrupami mężczyzn, występowały istotne różnice wiekowe, Mc oraz wskaźników: BMI, Queteleta, Rohrera i smukłości. Wnioski: Powyższe dane wskazują, że pomimo braku różnic wieku między badanymi kobietami i mężczyznami z podobnym lub różnym BMI istnieje wyraźna somatyczna determinacja płciowa, natomiast w obrębie tej samej płci, różniącej się wskaźnikiem BMI, wiek badanych jest czynnikiem determinacji somatycznej. Wykazano też, że badane wskaźniki somatyczne mają różną moc predykcyjną w zakresie oceny nadwagi i stopnia otyłości badanych kobiet i mężczyzn.

    Full text: The use of fixed doses of radioiodine ( 131 I) simplifies the approach to treatment for Graves' disease (GD) patients with potential cost savings. In order to evaluate factors that may affect the outcome of 2 different regimens of 131 I, we prospectively examined 128 patients with overt thyrotoxicosis from GD, as confirmed by suppressed serum TSH, presence of TRAb, increased serum T 3 and FT 4 values. Group 1 comprised 76 patients who received a fixed dose of 10 mCi and Group 2=52 patients who received a fixed dose of 15 mCi. 36 patients did not use any antithyroid drugs and 92 patients used methimazole that was withdrawn at least 5 days before radioiodine administration. Antithyroid drugs treatment was restarted at least 7 days following 131 I therapy when needed. Baseline serum TSH and FT 4 levels were measured at 3, 6, 9 and 12 months after treatment. The groups were similar concerning age, gender, smoke, eye disease, goiter size, serum T 3 , FT 4 , TRAb, anti-Tg and anti-TPO levels as well as 24-hour 131 I or Tec-uptake values and thyroid scan. Clinical outcome was evaluated at the end of 1-year follow-up and cure of hyperthyroidism was defined as clinical and laboratory evidence of either euthyroidism or hypothyroidism in the absence of antithyroid drugs. The cure rate obtained was similar in groups 1 and 2: 73.7% and 80.8%, respectively (p=0.35). Hypothyroidism was diagnosed in 56.5% and 71.15% of the patients from groups 1 and 2, respectively (p=0.13). There was no correlation between clinical features, thyroid uptake, antibodies, serum hormones and outcome. However, logistic regression analysis demonstrated that patients with larger thyroids (weight >60 g) that, consequently, received a lower dose of radioiodine in MBq/g, had 2.4 times less chance to cure (95% Cl=1.18-4.96). The use of fixed doses of radioiodine ( 131 I) simplifies the approach to treatment for Graves' disease (GD) patients with potential cost savings. In order to evaluate

Powszechnie, jako dodatek mineralny do cementu stosowany jest granulowany żużel wielkopiecowy, popiół lotny, czy też pył krzemionkowy. Podczas obróbki kruszywa stosowanego do produkcji mas mineralno-asfaltowych (MMA powstają duże ilości odpadów pylastych. Utylizacja tych odpadów stanowi obecnie duży problem w wielu wytwórniach MMA. W pracy dokonano analizy możliwości zastosowania odpadowego pyłu bazaltowego do produkcji zaprawy cementowej. Najpierw zbadano właściwości fizyczne i chemiczne zastosowanego pyłu bazaltowego. Celem określenia wpływu dodatku pyłu bazaltowego na niektóre właściwości zapraw przygotowano cztery mieszanki, w których pył bazaltowy stanowił częściowy zamiennik piasku w ilości 0-30% masy piasku. Badania doświadczalne dotyczyły analizy wpływu pyłu na wytrzymałość zapraw na ściskanie i zginanie po 2, 28 i 56 dniach dojrzewania próbek, mrozoodporności, nasiąkliwość oraz zdolności do kapilarnego podciągania wody. Następnie przeprowadzono badania dotyczące wpływu dodatku pyłu bazaltowego na mikrostrukturę oraz porowatość zaprawy. Wyniki przeprowadzonych badań wskazują na to, że pył bazaltowy może być stosowany do produkcji zapraw cementowych, jako substytut piasku naturalnego. Zastąpienie części piasku w zaprawie cementowej przez pył bazaltowy pozwoli na zagospodarowanie odpadu przemysłowego oraz wpłynie na poprawę niektórych cech zaprawy cementowej.

    Complex interventions are widely used in health care, public health, education, criminology, social work, business, and welfare. They have increasingly become the subject of systematic reviews and are challenging to effectively report. The Complex Interventions Methods Workgroup developed an extension to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Complex Interventions (PRISMA-CI). Following the EQUATOR Network guidance for Preferred Reporting Items for Systematic Reviews and Meta-Analysis extensions, this Explanation and Elaboration (EE) document accompanies the PRISMA-CI checklist to promote consistency in reporting of systematic reviews of complex interventions. The EE document explains the meaning and rationale for each unique PRISMA-CI checklist item and provides examples to assist systematic review authors in operationalizing PRISMA-CI guidance. The Complex Interventions Workgroup developed PRISMA-CI as an important start toward increased consistency in reporting of systematic reviews of complex interventions. Because the field is rapidly expanding, the Complex Interventions Methods Workgroup plans to re-evaluate periodically for the need to add increasing specificity and examples as the field matures.

Celem pracy było przedstawienie  zależności biomechanicznych oraz okoliczności towarzyszących powstawaniu WAD wynikających z badań populacyjnych, statystyk firm ubezpieczeniowych oraz analizy zapisów rejestratorów zderzeń montowanych przez producentów samochodów. Znajomość technicznych aspektów okoliczności powstawania WAD może ułatwić medyczną ocenę tego rodzaju następstw.

  9. Isenção da ciência, neutralidade da análise

    Full Text Available O artigo discute as relações entre a psicanálise e a ciência, especialmente no que tange aos seus métodos de investigação e trabalho. Para isso, tomamos como objeto a noção de neutralidade, tal como podemos apreendê-la na clínica da psicanálise, para confrontá-la com o que chamamos de isenção no campo da ciência, que não quer dizer outra coisa que a neutralidade proposta lá. Veremos que, apesar da clara filiação da noção psicanalítica para com a noção vinda da ciência, a neutralidade clínica da psicanálise toma outro rumo, que se pode mesmo opor ao sentido do termo na ciência. Enquanto em ciência o termo quer significar um processo de purificação e de seleção, em psicanálise ele surge como a exigência de nada selecionar.

    Full Text Available Objectives. This study assessed the correlation between performance intelligence and the postoperative cochlear implant (CI outcome in Korean-speaking children. In addition, the relationship between the performance intelligence subscales and the post-CI speech outcome was evaluated. Materials and Methods. Thirteen pediatric CI users (five males, eight females; median age at implantation 6.2 (range 1.3–14.2 years; median age at intelligence test 9.3 (range 5–16 years who were tested using the Korean Educational Development Institute-Wechsler Intelligence Scale for children were studied. The correlations between the intelligence scores and 1-2 years postoperative Categories of Auditory Performance (CAP scores and between subscales of performance and 1-2 years postoperative CAP scores were analyzed. Results. There was no correlation between the categories of verbal intelligence quotient (IQ and performance IQ for “mentally retarded” and “average,” respectively (Spearman’s rho = 0.42, P=0.15. There was a strong correlation between performance IQ and the postoperative CAP scale (Spearman’s rho = 0.8977, P=0.0008. “Picture arrangement” and “picture completion,” reflecting social cognition, were strongly correlated with the postoperative CAP scales. Conclusion. Performance intelligence, especially social cognition, was strongly related to the postoperative CI outcome of cochlear implant users. Therefore, auditory rehabilitation, including social rehabilitation, should maximize the postoperative CI outcomes.

    Photoelectric photometry and spectral observations of the symbiotic star CI Cyg were carried out at the Crimean Astrophysical Observatory from April, 1975 through December, 1976. The instrumental photometric system used was close to the UBV. Considerable light variations and spectral changes have been recorded during the period of the observations. Yellow, blue and ultraviolet amplitudes were equal to 2.3, 3.0 and 3sub(m).3 correspondingly. The brightness of CI Cyg reached maximal value in June - July, 1975 when spectrum was F5 with Hsub(..cap alpha..) and Hsub(..beta..) in emission. A sharp and deep minimum in the light curves of CI Cyg was observed during the period of the highest brightness. It was caused by the eclipse of the hot component by the cold one in the binary system.

    The voltage-sensing domain (VSD) is the common scaffold responsible for the functional behavior of voltage-gated ion channels, voltage sensitive enzymes, and proton channels. Because of the position of the voltage dependence of the available VSD structures, at present, they all represent the activated state of the sensor. Yet in the absence of a consensus resting state structure, the mechanistic details of voltage sensing remain controversial. The voltage dependence of the VSD from Ci-VSP (Ci-VSD) is dramatically right shifted, so that at 0 mV it presumably populates the putative resting state. Appropriate biochemical methods are an essential prerequisite for generating sufficient amounts of Ci-VSD protein for high-resolution structural studies. Here, we present a simple and robust protocol for the expression of eukaryotic Ci-VSD in Escherichia coli at milligram levels. The protein is pure, homogeneous, monodisperse, and well-folded after solubilization in Anzergent 3-14 at the analyzed concentration (~0.3 mg/mL). Ci-VSD can be reconstituted into liposomes of various compositions, and initial site-directed spin labeling and electron paramagnetic resonance (EPR) spectroscopic measurements indicate its first transmembrane segment folds into an α-helix, in agreement with the homologous region of other VSDs. On the basis of our results and enhanced relaxation EPR spectroscopy measurement, Ci-VSD reconstitutes essentially randomly in proteoliposomes, precluding straightforward application of transmembrane voltages in combination with spectroscopic methods. Nevertheless, these results represent an initial step that makes the resting state of a VSD accessible to a variety of biophysical and structural approaches, including X-ray crystallography, spectroscopic methods, and electrophysiology in lipid bilayers.

    Full Text Available A work of art – a link between the present and the past. History and patriotism in non-professional art In her article, the author discusses art of non-professional artists who shape the national identity in an original way. In the former professional art, the works which illustrated and uplifted history were very popular. This phenomenon is still present among folk, naive, intuitive artists, generally speaking – non-professionals. The work of their hands and imagination is a tool serving the purpose of national values and ideas, and is sometimes the basis for broader considerations on the human condition. They balance between historical facts and ahistorical generalities. The martyrdom of the Polish nation with emphasis on the events of WWII has been inspiring artists, stimulating their imagination and artistic creation. Therefore numerous ‘monuments of patriotic art’ can be found in the wood sculpture, ceramics, painting, and glass painting works from the art collection of the Toruń Maria Znamierowska-Prüfferowa Ethnographic Museum.   Dzieło sztuki na granicy przeszłości i przyszłości.

  5. A mutation in Myo15 leads to Usher-like symptoms in LEW/Ztm-ci2 rats.

    Directory of Open Access Journals (Sweden)

    Nadine Held

    Full Text Available The LEW/Ztm-ci2 rat is an animal model for syndromal deafness that arose from a spontaneous mutation. Homozygous animals show locomotor abnormalities like lateralized circling behavior. Additionally, an impaired vision can be observed in some animals through behavioral studies. Syndromal deafness as well as retinal degeneration are features of the Usher syndrome in humans. In the present study, the mutation was identified as a base substitution (T->C in exon 56 of Myo15, leading to an amino acid exchange from leucine (Leu to proline (Pro within the carboxy-terminal MyTH4 domain in the proteins' tail region. Myo15 mRNA was expressed in the retina as demonstrated for the first time with the help of in-situ hybridization and PCR. To characterize the visual phenotype, rats were examined by scotopic and photopic electroretinography and, additionally, histological analyses of the retinas were conducted. The complete loss of sight was detected along with a severe degeneration of photoreceptor cells. Interestingly, the manifestation of the disease does not solely depend on the mutation, but also on environmental factors. Since the LEW/Ztm-ci2 rat features the entire range of symptoms of the human Usher syndrome we think that this strain is an appropriate model for this disease. Our findings display that mutations in binding domains of myosin XV do not only cause non-syndromic hearing loss but can also lead to syndromic disorders including retinal dysfunction.

  6. CI+MBPT calculations of Ar I energies, g factors, and transition line strengths

    Excited states of noble gas atoms present certain challenges to atomic theory for several reasons: first, relativistic effects are important and LS coupling is not optimal; second, energy intervals can be quite small, leading to strong mixing of states; third, many-body perturbation theory for hole states does not converge well. Previously, some attempts were made to solve this problem, using for example the all-order coupled-cluster approach and particle-hole configuration-interaction many-body perturbation theory (CI-MBPT) with modified denominators. However, while these approaches were promising, the accuracy was still limited. In this paper, we calculate Ar I energies, g factors, and transition amplitudes using ab initio CI-MBPT with eight valence electrons to avoid the problem of slow convergence of MBPT due to strong interaction between 3p and 3s states. We also included in CI many dominant states obtained by double excitations of the ground state configuration. Thus perturbation corrections were needed only for 1s, 2s, 2p core electrons non-included in valence-valence CI, which are quite small. We found that energy, g factors, and electric dipole matrix elements are in reasonable agreement with experiments. It is noteworthy that the theory agreed well with accurately measured g factors. Experimental oscillator strengths have large uncertainty, so in some cases we made a comparison with average values.

  14. Coupling between the voltage-sensing and phosphatase domains of Ci-VSP.

    The Ciona intestinalis voltage sensor-containing phosphatase (Ci-VSP) shares high homology with the phosphatidylinositol phosphatase enzyme known as PTEN (phosphatase and tensin homologue deleted on chromosome 10). We have taken advantage of the similarity between these proteins to inquire about the coupling between the voltage sensing and the phosphatase domains in Ci-VSP. Recently, it was shown that four basic residues (R11, K13, R14, and R15) in PTEN are critical for its binding onto the membrane, required for its catalytic activity. Ci-VSP has three of the basic residues of PTEN. Here, we show that when R253 and R254 (which are the homologues of R14 and R15 in PTEN) are mutated to alanines in Ci-VSP, phosphatase activity is disrupted, as revealed by a lack of effect on the ionic currents of KCNQ2/3, where current decrease is a measure of phosphatase activity. The enzymatic activity was not rescued by the introduction of lysines, indicating that the binding is an arginine-specific interaction between the phosphatase binding domain and the membrane, presumably through the phosphate groups of the phospholipids. We also found that the kinetics and steady-state voltage dependence of the S4 segment movement are affected when the arginines are not present, indicating that the interaction of R253 and R254 with the membrane, required for the catalytic action of the phosphatase, restricts the movement of the voltage sensor.

    Brachyury, a T-box transcription factor, is expressed in ascidian embryos exclusively in primordial notochord cells and plays a pivotal role in differentiation of notochord cells. Previously, we identified approximately 450 genes downstream of Ciona intestinalis Brachyury (Ci-Bra), and characterized the expression profiles of 45 of these in differentiating notochord cells. In this study, we looked for cisregulatory sequences in minimal enhancers of 20 Ci-Bra downstream genes by electroporating region within approximately 3 kb upstream of each gene fused with lacZ. Eight of the 20 reporters were expressed in notochord cells. The minimal enchancer for each of these eight genes was narrowed to a region approximately 0.5-1.0-kb long. We also explored the genome-wide and coordinate regulation of 43 Ci-Bra-downstream genes. When we determined their chromosomal localization, it became evident that they are not clustered in a given region of the genome, but rather distributed evenly over 13 of the 14 pairs of chromosomes, suggesting that gene clustering does not contribute to coordinate control of the Ci-Bra downstream gene expression. Our results might provide Insights Into the molecular mechanisms underlying notochord formation in chordates.

    Low temperature combustion concepts are studied recently to simultaneously reduce NOX and soot emissions. Optical studies are performed to study gasoline PPC in CI engines to investigate in-cylinder combustion and stratification. It is imperative to perform emission measurements and interpret the results with combustion images. In this work, we attempt to investigate this during the transition from CI to HCCI mode for FACE I gasoline (RON = 70) and its surrogate, PRF70. The experiments are performed in a single cylinder optical engine that runs at a speed of 1200 rpm. Considering the safety of engine, testing was done at lower IMEP (3 bar) and combustion is visualized using a high-speed camera through a window in the bottom of the bowl. From the engine experiments, it is clear that intake air temperature requirement is different at various combustion modes to maintain the same combustion phasing. While a fixed intake air temperature is required at HCCI condition, it varies at PPC and CI conditions between FACE I gasoline and PRF70. Three zones are identified 1) SOI = -180 to -80 CAD (aTDC) is HCCI zone 2) SOI = -40 to -20 CAD (aTDC) is PPC zone 3) After SOI = -15 CAD (aTDC) is CI zone. Combustion duration, ignition delay, start of combustion and CA90 (crank angle at which 90% of fuel burnt) are comparable between FACE I gasoline and PRF70. The combustion images show a prominent soot flame at CI condition, while only blue coloured premixed flames are visible at PPC condition for both the fuels. PRF70 seems to have a pronounced premixed effect when compared to FACE I gasoline at early injections, showing a decreased level of stratification. NOX emission and soot concentration decreases from CI condition and attains a constant zero value at HCCI condition for both FACE I gasoline and PRF70. CO and CO2 emissions matches between FACE I gasoline and PRF70 at PPC and CI condition, while CO emission is lower for PRF70 at HCCI condition.

  5. The maternal genes Ci-p53/p73-a and Ci-p53/p73-b regulate zygotic ZicL expression and notochord differentiation in Ciona intestinalis embryos.

    I isolated a Ciona intestinalis homolog of p53, Ci-p53/p73-a, in a microarray screen of rapidly degraded maternal mRNA by comparing the transcriptomes of unfertilized eggs and 32-cell stage embryos. Higher expression of the gene in eggs and lower expression in later embryonic stages were confirmed by whole-mount in situ hybridization (WISH) and quantitative reverse transcription-PCR (qRT-PCR); expression was ubiquitous in eggs and early embryos. Knockdown of Ci-p53/p73-a by injection of antisense morpholino oligonucleotides (MOs) severely perturbed gastrulation cell movements and expression of notochord marker genes. A key regulator of notochord differentiation in Ciona embryos is Brachyury (Ci-Bra), which is directly activated by a zic-like gene (Ci-ZicL). The expression of Ci-ZicL and Ci-Bra in A-line notochord precursors was downregulated in Ci-p53/p73-a knockdown embryos. Maternal expression of Ci-p53/p73-b, a homolog of Ci-p53/p73-a, was also detected. In Ci-p53/p73-b knockdown embryos, gastrulation cell movements, expression of Ci-ZicL and Ci-Bra in A-line notochord precursors, and expression of notochord marker gene at later stages were perturbed. The upstream region of Ci-ZicL contains putative p53-binding sites. Cis-regulatory analysis of Ci-ZicL showed that these sites are involved in expression of Ci-ZicL in A-line notochord precursors at the 32-cell and early gastrula stages. These results suggest that p53 genes are maternal factors that play a crucial role in A-line notochord differentiation in C. intestinalis embryos by regulating Ci-ZicL expression.

    Full Text Available Ocena możliwości implementacji standardów IPSAS do systemu rachunkowości podmiotów sektora publicznego w Polsce In recent years, there has been a noticeable increase in activity in the field of standardization of public sector accounting, which has an international scope and takes the form of the International Public Sector Accounting Standards (IPSAS. It has been planned that the EU Member States, and consequently Poland, will implement obligatory uniform accounting standards in the public sector – EPSAS – which are to be largely based on the content of IPSAS. The purpose of this paper is to assess the possibilities and factors of IPSAS implementation in the accounting system of public finance sector entities in Poland in relation to the currently applicable accounting regulations and the intelligibility criterion for potential users. The assessment was carried out based on a study of the foreign and domestic literature and existing legislation, while for the conclusions, the deductive and synthetic methods were used. The paper demonstrates that despite the relatively long period of operation of IPSAS, their level of implementation into the accounting system of public sector entities in Poland is negligible. The same applies to the works on the European standards, EPSAS, which have been significantly delayed in relation to the original assumptions. Knowledge of international standards is weak, and consequently their dissemination too. In spite of IPSAS implementation problems, there are still a number of reasons for their use. One of the arguments in favor of introducing uniform standards on the European market is the fact that the common market is in operation, and another one is the strong embedding of the need to consolidate the public sector’s international financial data at the central level of the Community. The conducted research confirmed the possibility of implementing IPSAS into Polish public sector entities’ accounting

    1975-12-01

    The Rorschach protocols of 43 males consecutively admitted to a university outpatient clinic were scored for frequency of the 20 Wheeler signs of homosexuality. Based on case history data, patients were assigned to homosexual, sex-role disturbed, or normal-control groups. In addition to the traditional group comparison the results were analyzed to yield P (Ci/Rj); that is, the probability of criterion group membership given test indicator. Both the homosexual and sex-role disturbed group displayed significantly more Wheeler signs than normals. Furthermore, given a Wheeler sign score of 15%, .75 of the predicted-homosexual group would be correctly classified compared to a .21 baserate prediction. It was suggested that expressing results as P (Ci/Rj) provides information more relevant to the clinician than is provided by the traditional practice of reporting significant differences between groups.

    Full Text Available Otyłość jest chorobą określaną jako patologiczne zwiększenie ilości tkanki tłuszczowej, która w nadmiernej ilości wpływa negatywnie na stan zdrowia, długość życia i sprawność psychofizyczną. Osoby z nadmierną masą ciała, w której zawartość tłuszczu stanowi proporcjonalnie wysoki odsetek, w porównaniu z osobami o niższej masie ciała są fizjologicznie mniej wydolni, a ich potencjał motoryczny jest niższy. W otyłości u osób dorosłych dochodzi przede wszystkim do zwiększenia rozmiarów komórek tłuszczowych. W przypadku dzieci obserwujemy przyrost liczby komórek tłuszczowych, które mogą się przyczynić do rozwoju otyłości w wieku dorosłym, gdyż zwiększenie liczby komórek jest procesem nieodwracalnym. Często rodzice aż do momentu wystąpienia znacznej otyłości nie postrzegają nadmiernej masy ciała dziecka w kategoriach problemu zdrowotnego. Istotna staje się więc rola służby zdrowia w prowadzeniu działań prewencyjnych, skierowanych na działania np. fitness clubów odpowiednio przygotowanych do podejmowania tego typu zadań. Ogólnie przyjęte zasady dawkowania ćwiczeń w treningu zdrowotnym fitness osób dorosłych oraz dzieci i młodzieży są podobne. Różnią się czasem trwania, częstotliwością podejmowania aktywności oraz stosowanymi obciążeniami. Treningi fitness obejmują głównie wytrzymałościowe formy ćwiczeń, takie jak ćwiczenia aerobowe na urządzeniach typu cardio mające za zadanie przede wszystkim uaktywnić i zredukować nadmiar tkanki tłuszczowej. Inną formą zajęć usprawniających powinny być ćwiczenia oporowe uwzględniające stosowanie urządzeń izotonicznych. Należy przy tym zwrócić szczególną uwagę na dobór ćwiczeń, obciążenie oraz kontrolę postępów. Równocześnie zaleca się stosowanie monitoringu zakresów HR każdej sesji treningu aerobowego i oporowego. Jako uzupełnienie proponowane są ćwiczenia gibkościowe wykonywane jako

    Full Text Available CI therapy is effective in patients with relatively good levels of residual arm function but its applicability to patients with low functioning hemiparesis is not entirely clear. In the present study we examined the feasibility and efficacy of the CI therapy concept in patients with very limited upper arm function prior to treatment, and further tested how the length of daily shaping training and constraining the good arm affects treatment outcome. In a baseline-controlled design, 65 chronic patients were treated with 2 weeks of modified CI therapy. Patients were randomly allocated to four treatment groups receiving 90 or 180 minutes of daily shaping training applied with or without constraint respectively. Outcome was measured through the Reliable Change Index, which was calculated for parameters of motor function, health and psychological wellbeing. Follow-up data were collected at 6 and 12 months. Two analyses were conducted, a whole-group analysis across all 65 participants and a subgroup analysis contrasting the four treatment variants.The whole-group analysis showed a significant treatment effect, which was largely sustained after one year. The subgroup analysis revealed a mixed picture: while improvements against the baseline period were observed in all four subgroups, 180 minutes of daily shaping training coupled with the constraint yielded better outcome on the MAL but not the WMFT, while for 90 minutes of training the level of improvement was similar for those who wore the constraint and those who did not. Together these results suggest that, at least in those patients available for follow up measures, modified CI therapy induces sustained improvements in motor function in patients with chronic low-functioning hemiparesis. The absence of clear differences between the four treatment variants points to a complex relationship between the length of daily shaping training and the constraint in this patient group which is likely to be

  13. Time course of auditory streaming: Do CI users differ from normal-hearing listeners?

    2014-07-01

    Full Text Available In a complex acoustical environment with multiple sound sources the auditory system uses streaming as a tool to organize the incoming sounds in one or more streams depending on the stimulus parameters. Streaming is commonly studied by alternating sequences of signals. These are often tones with different frequencies. The present study investigates stream segregation in cochlear implant (CI users, where hearing is restored by electrical stimulation of the auditory nerve. CI users listened to 30-s long sequences of alternating A and B harmonic complexes at four different fundamental frequency separations, ranging from 2 to 14 semitones. They had to indicate as promptly as possible after sequence onset, if they perceived one stream or two streams and, in addition, any changes of the percept throughout the rest of the sequence. The conventional view is that the initial percept is always that of a single stream which may after some time change to a percept of two streams. This general build-up hypothesis has recently been challenged on the basis of a new analysis of data of normal-hearing listeners which showed a build-up response only for an intermediate frequency separation. Using the same experimental paradigm and analysis, the present study found that the results of CI users agree with those of the normal-hearing listeners: (i the probability of the first decision to be a one-stream percept decreased and that of a two-stream percept increased as Δf increased, and (ii a build-up was only found for 6 semitones. Only the time elapsed before the listeners made their first decision of the percept was prolonged as compared to normal-hearing listeners. The similarity in the data of the CI user and the normal-hearing listeners indicates that the quality of stream formation is similar in these groups of listeners.

    Costlier and depleting fossil fuels are prompting researchers to use edible as well as non-edible vegetable oils as promising alternative to petro-diesel. The higher viscosity of vegetable oils leads to problem in pumping, atomization and spray characteristics. The improper mixing of vegetable oils with air leads to incomplete combustion. The best way to use vegetable oils as fuel in compression ignition (CI) engines is to convert it into biodiesel. Biodiesel is a methyl or ethyl ester of fatty acids made from vegetable oils (both edible and non-edible) and animal fat. The main feedstock for biodiesel production can be non-edible oil obtained from Jatropha curcas plant. Jatropha curcas plant can be cultivated on different terrains in India under extreme climatic conditions. Biodiesel can be used in its pure form or as a blend with petro-diesel in different proportions. It is being used in CI engines because it has properties similar to petro-diesel. The aim of this paper is to analyze suitability of petro-diesel blended with biodiesel in varying proportions in CI engines. For this purpose, a stationary single-cylinder four-stroke CI engine was tested with diesel blended with Jatropha biodiesel in 0%, 5%, 20%, 50%, 80% and 100%. Comparative measures of specific fuel consumption (SFC), brake thermal efficiency, smoke opacity, HC, CO2, CO, O2, NOX have been presented and discussed. Engine performance in terms of comparable brake thermal efficiency and SFC with lower emissions (HC, CO2, CO) was observed with B20 fuel compared to petro-diesel. Volumetric efficiency showed almost no variation for all the blends. Important observations related to noise and vibrations during testing have also been discussed.

    During development, neural precursors divide to produce new precursors and cells that differentiate as neurons and glia. In Drosophila, apicobasal polarity and orientation of the mitotic spindle play important roles in specifying the progeny of neural precursors for different fates. We examined orientation of zebrafish spinal cord precursors using time-lapse imaging and tested the function of protein kinase C, iota (PrkCi), a member of the Par complex of proteins necessary for apicobasal pola...

    Full Text Available Klozapina, choć uważana za bardzo skuteczny lek przeciwpsychotyczny, jest stosowana rzadziej, niż wynikałoby z przesłanek klinicznych wspierających jej stosowanie. Co najmniej 1/3 chorych ze schizofrenią spełnia kliniczne kryteria lekooporności, charakteryzuje się wysokim ryzykiem samobójstwa lub reaguje nasilonymi objawami pozapiramidowymi na inne leki przeciwpsychotyczne. Możliwym powodem relatywnie rzadkiego sięgania po klozapinę w praktyce klinicznej jest postrzeganie leku jako obarczonego poważnymi objawami niepożądanymi. Agranulocytoza i inne dyskrazje krwi są dobrze znane, a zasady prewencji – uporządkowane zaleceniami. O innych objawach niepożądanych, również tych potencjalnie niebezpiecznych (kardiomiopatia, zapalenia mięśnia sercowego, niedrożność jelit czy drgawki wiadomo mniej. Ryzyko wystąpienia groźnych powikłań kuracji klozapiną można jednak zminimalizować, a same powikłania – wykrywać i leczyć, pod warunkiem zachowania czujności diagnostycznej. Świadomość ryzyka i korzyści związanych ze stosowaniem klozapiny to warunek konieczny skutecznego i bezpiecznego użycia tego leku oraz pełnego wykorzystania jego niezwykłych właściwości.

    Full Text Available Currently, alternative fuels are being investigated in detail for application in compression ignition (CI engines resulting in exciting potential opportunities to increase energy security and reduce gas emissions. Biodiesel is one of the alternative fuels which is renewable and environmentally friendly and can be used in diesel engines with little or no modifications. The objective of this study is to investigate the effects of biodiesel types and biodiesel fraction on the emission characteristics of a CI engine. The experimental work was carried out on a four-cylinder, four-stroke, direct injection (DI and turbocharged diesel engine by using biodiesel made from waste oil, rapeseed oil, corn oil and comparing them to normal diesel. The fuels used in the analyses are B10, B20, B50, B100 and neat diesel. The engine was operated over a range of engine speeds. Based on the measured parameters, detailed analyses were carried out on major regulated emissions such as NOx, CO, CO2, and THC. It has been seen that the biodiesel types (sources do not result in any significant differences in emissions. The results also clearly indicate that the engine running with biodiesel and blends have higher NOx emission by up to 20%. However, the emissions of the CI engine running on neat biodiesel (B100 were reduced by up to 15%, 40% and 30% for CO, CO2 and THC emissions respectively, as compared to diesel fuel at various operating conditions.

    In the voltage sensing phosphatase, Ci-VSP, a voltage sensing domain (VSD) controls a lipid phosphatase domain (PD). The mechanism by which the domains are allosterically coupled is not well understood. Using an in vivo assay, we find that the inter-domain linker that connects the VSD to the PD is essential for coupling the full-length protein. Biochemical assays show that the linker is also needed for activity in the isolated PD. We identify a late step of VSD motion in the full-length protein that depends on the linker. Strikingly, this VSD motion is found to require PI(4,5)P2, a substrate of Ci-VSP. These results suggest that the voltage-driven motion of the VSD turns the enzyme on by rearranging the linker into an activated conformation, and that this activated conformation is stabilized by PI(4,5)P2. We propose that Ci-VSP activity is self-limited because its decrease of PI(4,5)P2 levels decouples the VSD from the enzyme. PMID:20364128

    Highlights: ► Camelina sativa as a potential source of alternative fuel. ► Neat camelina sativa oil as a fuel for CI engine. ► The engine performance and emissions of CI engine fuelled with neat camelina sativa oil. ► Comparison of rate of heat release for camelina sativa oil and diesel oil. - Abstract: The paper describes the results of the tests of CI Perkins 1104C-44 engine fuelled with camelina sativa oil. The engine was not especially calibrated for fuelling with the vegetable fuel. During the test the engine performance and emissions were analysed. For comparison the same speed characteristic was examined for standard fuelling of the engine with diesel oil. In order to understand the engine performance and emission the mass fraction burnt and the rate of heat release was calculated and compared for the same energy provided to the engine cylinder with the injected fuels. The results show that there is possible to receive relatively good engine performance for fuelling the engine with camelina sativa oil but there is a need to change the calibration parameters of the engine fuel system when the engine is fuelled with this fuel.

    Enteropathogenic Escherichia coli utilise a filamentous type III secretion system to translocate effector proteins into host gut epithelial cells. The primary constituent of the extracellular component of the filamentous type III secretion system is EspA. This forms a long flexible helical conduit between the bacterium and host and has a structure almost identical to that of the flagella filament. We have inserted the D3 domain of FliCi (from Salmonella typhimurium) into the outer domain of EspA and have studied the structure and function of modified filaments when expressed in an enteropathogenic E. coli espA mutant. We found that the chimeric protein EspA-FliCi filaments were biologically active as they supported protein secretion and translocation [assessed by their ability to trigger actin polymerisation beneath adherent bacteria (fluorescent actin staining test)]. The expressed filaments were recognised by both EspA and FliCi antisera. Visualisation and analysis of the chimeric filaments by electron microscopy after negative staining showed that, remarkably, EspA filaments are able to tolerate a large protein insertion without a significant effect on their helical architecture.

    In order to check the heterogeneity of the CI chondrites and determine the average composition of this group of meteorites, we analyzed a series of six large chips (weighing between 0.6 and 1.2 g) of Orgueil prepared from five different stones. In addition, one sample from each of Ivuna and Alais was analyzed. Although the sizes of the chips used in this study were “large”, our results show evidence for minor chemical heterogeneity in Orgueil, particularly for alkali elements and U. After removal of one outlier sample, the spread of the results is considerably reduced. For most of the 46 elements analyzed in this study, the average composition calculated for Orgueil is in very good agreement with previous CI estimates. This average, obtained with a “large” mass of samples, is analytically homogeneous and is suitable for normalization purposes. Finally, the Cu and Zn isotopic ratios are homogeneously distributed within the CI parent body with a spread of less than 100 ppm per atomic mass unit (amu).

    This paper reports on commercial mitigation techniques used in remediating a 2200 pCi/L public building. In March of 1989 EPA and Pa. DER officials were amazed to discover a school in Pennsylvania with levels in its library of 2200 pCi/L. The library was a 30 year old, three story slab-on-grade structure more like a commercial building than a typical school structure. It had three separate and complex HVAC systems. Initial diagnostics indicated radon levels under the slab at over 80,000 pCi/L. Further investigations revealed major entry routes and a HVAC system terribly out of balance. Remediation consisted of installing a complex sub-slab depressurization system with an exterior commercial fan unit, major entry route sealing, and working closely with a mechanical contractor to bring the HVAC systems back into balance. Initial post remediation testing showed a 99% drop in radon levels. Refinements to the system are still in progress

    Due to the large number of files and their complex structure, managing data generated during natural hazards experiments requires scalable and specialized tools. DesignSafe-CI (https://www.designsafe-ci.org/) is a web-based research platform that provides computational tools to analyze, curate, and publish critical data for natural hazards research making it understandable and reusable. We present a use case from a series of Direct Simple Shear (DSS) experiments in which we used DS-CI to post-process, visualize, publish, and enable further analysis of the data. Current practice in geotechnical design against earthquakes relies on the soil's plasticity index (PI) to assess liquefaction susceptibility, and cyclic softening triggering procedures, although, quite divergent recommendations on recommended levels of plasticity can be found in the literature for these purposes. A series of cyclic and monotonic direct simple shear experiments was conducted on three low-plasticity fine-grained mixtures at the same plasticity index to examine the effectiveness of the PI in characterization of these types of materials. Results revealed that plasticity index is an insufficient indicator of the cyclic behavior of low-plasticity fine-grained soils, and corrections for pore fluid chemistry and clay minerology may be necessary for future liquefaction susceptibility and cyclic softening assessment procedures. Each monotonic, or cyclic experiment contains two stages; consolidation and shear, which include time series of load, displacement, and corresponding stresses and strains, as well as equivalent excess pore-water pressure. Using the DS-CI curation pipeline we categorized the data to display and describe the experiment's structure and files corresponding to each stage of the experiments. Two separate notebooks in Python 3 were created using the Jupyter application available in DS-CI. A data plotter aids visualizing the experimental data in relation to the sensor from which it was

    Full Text Available Kamicą układu moczowego nazywamy schorzenie, w którym wytwarzane są złogi w obrębie nerek lub dróg moczowych. Obecnie obserwuje się wzrost częstości występowania kamicy. Szacuje się, iż częstość występowania kamicy układu moczowego wynosi 0,5-5% w grupie dorosłych i 0,1-5% u dzieci. Istotnym problemem jest wykrywanie złogów u małych dzieci, również u niemowląt. Biorąc pod uwagę coraz częstsze wykrywanie kamicy układu moczowego, jej nawrotowość i powikłania, ważne jest wypracowanie schematów leczniczych skutecznych i jednocześnie bezpiecznych, nawet przy konieczności ich kilkukrotnego powtarzania. Postępowanie zachowawcze jest skuteczne w 80%, w przypadkach złogów o wielkości do 4 mm. Powszechnie stosowane do lat 80. XX wieku leczenie operacyjne związane z nacięciem miąższu nerki obecnie w większości przypadków zastępowane jest metodami mniej inwazyjnymi, takimi jak ESWL, PCNL, URSL, a wskazania do leczenia chirurgicznego kamicy zostały znacznie ograniczone. W niniejszej pracy przedstawiono przypadek pacjentki z kamicą układu moczowego leczonej kilkakrotnie metodą ESWL bez efektu, a następnie z uwagi na obecność złogów w moczowodzie za pomocą URSL. Jednym z powikłań po zabiegu ESWL może być „droga kamieni”. Po wykonaniu zabiegu ESWL pacjent wymaga monitorowania poprzez wykonywanie badań USG, co pozwala na szybkie uwidocznienie powikłania w postaci „drogi kamieni” i wdrożenie dodatkowego postępowania ułatwiającego wydalenie złogów. „Droga kamieni” może spowodować utrudnienie odpływu moczu, co może być przyczyną dolegliwości bólowych oraz różnego stopnia poszerzeń moczowodów i układów kielichowo-miedniczkowych. Często wymaga interwencji zabiegowej w trybie pilnym. W ciągu ostatnich dwudziestu lat nastą- piły w Polsce znaczne zmiany w sposobach leczenia kamicy moczowodowej.

Neste estudo, após um breve levantamento histórico-comparativo com a situação alemã do Entre Guerras, tecemos algumas críticas sobre a atual produção científica brasileira nas Ciências Humanas e ao atrelamento de nossas universidades públicas aos modelos internacionais e cientificistas de produtividade. E, também, tentamos debater como a corrupção científica tem se construído e fortalecido por causa da enorme pressão do “publicar ou perecer” e da adoção do Sistema Qualis, que têm induzido nossos cientistas a optar por consagrar temas já anteriormente pré-consagrados, evitando assim a crítica, anulando possíveis questionamentos, estimulando a publicação de “artigos-placebo” e impedindo, em última análise, o desenvolvimento científico e tecnológico do país. Abstract: Before the advent of the Qualis System, skewed research always seemed to be an easy way to obtain funding, recognition and privatization of the university machine in the hands of a few scientific groups, as for a long while, the area of medicine and its somewhat controversial relationships with the pharmaceutical industry has shown us. In this study, after a brief comparative-historical survey with the German situation of interwar period, some criticism have been weaved about the current Brazilian scientific production in the humanities and the bundling of our public universities to international and scientificist productivity models.

    Full Text Available Cirrus clouds remain one of the key uncertainties in atmospheric research. To better understand the properties and physical processes of cirrus clouds, accurate large-scale observations from satellites are required. Artificial neural networks (ANNs have proved to be a useful tool for cirrus cloud remote sensing. Since physics is not modelled explicitly in ANNs, a thorough characterisation of the networks is necessary. In this paper the CiPS (Cirrus Properties from SEVIRI algorithm is characterised using the space-borne lidar CALIOP. CiPS is composed of a set of ANNs for the cirrus cloud detection, opacity identification and the corresponding cloud top height, ice optical thickness and ice water path retrieval from the imager SEVIRI aboard the geostationary Meteosat Second Generation satellites. First, the retrieval accuracy is characterised with respect to different land surface types. The retrieval works best over water and vegetated surfaces, whereas a surface covered by permanent snow and ice or barren reduces the cirrus detection ability and increases the retrieval errors for the ice optical thickness and ice water path if the cirrus cloud is thin (optical thickness less than approx. 0.3. Second, the retrieval accuracy is characterised with respect to the vertical arrangement of liquid, ice clouds and aerosol layers as derived from CALIOP lidar data. The CiPS retrievals show little interference from liquid water clouds and aerosol layers below an observed cirrus cloud. A liquid water cloud vertically close or adjacent to the cirrus clearly increases the average retrieval errors for the optical thickness and ice water path, respectively, only for thin cirrus clouds with an optical thickness below 0.3 or ice water path below 5.0 g m−2. For the cloud top height retrieval, only aerosol layers affect the retrieval error, with an increased positive bias when the cirrus is at low altitudes. Third, the CiPS retrieval error is

    The SAC and SAC CI theories are formulated for actual calculations of singlet ground states and their excited states of arbitrary spin multiplicity. Approximations are considered for the variational methods since time-consuming terms are involved. The results of test calculations for singlet states have shown, with much smaller numbers of variables (sizes of the matrices involved), excellent agreement with the full CI and close-to-full CI results. This shows the utility of the SAC theory for ground states and especially of the SAC CI theory for excited states, since the slow convergence of the CI theory is much more critical for excited states than for ground states.

    2015-07-01

    Full Text Available O artigo apresenta duas teses de Heidegger: a interpretação da Crítica da Razão Pura como metafísica e a afirmação da permanência da metafísica na ciência moderna. Em seguida analisa as objeções que Loparic apresenta a essas teses no artigo A metafísica e o processo de objetificação,para enfim argumentar que suas contestações não se sustentam. Loparic afirma que  a Crítica da Razão Pura não se destina a investigar a quididade dos entes, mas as condições nas quais os juízos sintéticos a priori podem ser verdadeiros ou falsos, de modo que o problema tratado por Kant não seria ontológico, mas semântico. Loparic afirma ainda que a ciência moderna deixou o quadro ontológico da metafísica aristotélica, na medida em que não mais se destina a estudar os entes como tais, isto é, como uma coisa em si, mas tão somente investigar a resposta da natureza, mediante intervenção técnica no curso dos processos naturais e, portanto não há sequer resquício da metafísica na ciência moderna. Essas objeções apresentam dificuldades na medida em que o autor se utiliza do conceito tradicional de metafísica para tratar da filosofia de Heidegger. Argumenta-se que o sentido de metafísica para Heidegger não se restringe à concepção de metafísica da tradição, de modo que, constitui um equívoco analisar as teses heideggerianas em conformidade com a leitura da tradição.  Heidegger se pauta na indicação de que Kant se ocupa das condições de possibilidade da compreensão, isto é, do Dasein, enquanto o ente que coloca a pergunta sobre o ser e é nesta dimensão que a Crítica da Razão Pura é recepcionada como metafísica. No tocante à ciência, o filósofo afirma que, mesmo a ciência moderna tendo abandonado a representação de objetos, ela não renunciou e nem poderia renunciar à necessidade de a natureza fornecer dados que se possa calcular e de continuar sendo um sistema disponível de informação, de modo

    Interrogation/interpretation of cardiac implantable electronic devices (CIEDs) is frequently required in the emergency department (ED) or perioperative areas (OR) where resources to do this are often not available. CareLink Express (CLE; Medtronic, plc, Mounds View, MN, USA) is a technician-supported real-time remote interrogation system for Medtronic CIEDs. Using data from 136 US locations, this retrospective study was designed to assess CLE efficiency compared to traditional device management, and examine its findings. All 7,044 US CLE transmissions from the ED and OR (January 2012-October 2014) were compared to 217 traditional requests where CIED interrogations/interpretations were performed by calling industry representatives to these sites. CLE reduced the time to device interrogation/interpretation by 78%: 100 ± 140-22 ± 14 minutes, P < 0.0001, improving response time and consistency; ED: 82 ± 103-23 ± 18 minutes, P, ≤ 0.01; OR: 127 ± 181-17 ± 10 minutes, P < 0.0001. Actionable events (AE) (arrhythmia, device/lead abnormalities) were infrequent: 9.1% overall (ED: 9.9%; OR: 4.1%). Only 6.5% of patients with syncope/presyncope and 13.6% with a perceived shock had AE. AEs were more common in those with suspected device problems (30.4%) or audible alerts (52.6%). They were more likely in patients not enrolled in long-term remote monitoring (23.9% vs 8.2%, P < 0.0001) and in those with older CIED systems (7.4% in year 1 vs 31.0% after 10 years). The many patients with CIEDs, and the ability to quickly identify the minority with high-risk AE from the no/low-risk majority, strongly support CLE use in the ED and OR, sites which are expensive and prioritize efficiency. © 2015 Wiley Periodicals, Inc.

  17. Spacecraft COst REduction Team (SCORE): TQM/CI on a massive scale

    Bullard, Jerry D.

    1992-01-01

    The business of building satellites and space systems has matured. Few missions require, or can afford, excellent performance at any price. The new paradigm is doing more with less, providing quality systems at lower cost--in other words, doing our job 'Faster-Better-Cheaper.' The TRW Spacecraft COst REduction (SCORE) initiative was launched in 1990 by Daniel S. Goldin, then general manager of TRW's Space & Technology Group. The SCORE mission is to apply continuous improvement (CI) techniques to effect major reductions in the cost (our primary goal) and span time (as a corollary) required for the production of spacecraft. SCORE is a multi-year initiative that is having a profound effect on both the procedural and the cultural aspects of how we do business. The objectives of this initiative are being realized. The focus of this paper is not on the results of SCORE per se, but rather on the things we have leaned about how to do continuous improvement on a massive scale, with multilevel (hierarchical) CI teams. The following sections summarize the chronology of the SCORE initiative, from team formation to development of the year-end report for 1991. Lessons learned, the core of this presentation, are discussed--with particular focus on the unique aspects of SCORE. The SCORE initiative is continuing and, as a part of our evolving culture, will never end. It has resulted in profound insights into the way we do work and (the topic at hand) how to do CI for large and complex multidisciplinary development activities.

    1980-01-01

    We have developed a pulsed thermal neutron interrogation system and have demonstrated a sub-1-nCi/g assay sensitivity for high density TRU wastes contained in 200-liter barrels. We detect prompt fission neutrons, resulting in greatly enhanced sensitivity compared to techniques in which delayed fission neutrons are detected. We observe a linear assay response over at least three orders of magnitude in 235 U (or 239 Pu) mass. We also have measured a flat (to +-10%) interrogation flux profile throughout the volume of a 200-liter barrel filled with 200 kg of sand and vermiculite, which indicates flatness of response to fissile material at different locations within the barrel

    A project for the production of radiovaccines and other bio-medical products is presented which includes a radiation facility provided with a gamma ray source equivalent to 100,000 Ci of Co-60. The whole process incorporates novel basic features in virus production and inactivation steps. The former is carried out in animals previously subjected to immunodepression through electromagnetic radiation. The latter is obtained at low temperatures by using either electromagnetic or particle radiations. A vaccine manufacture process is shown to illustrate the utilization of ionizing radiations to obtain a foot and mouth disease virus (FMDV) vaccine with good antigenic quality and low cost. (author)

    The observations of CI Cyg were carried out with the Torun 60/90 cm Schmidt telescope with the objective prism giving a dispersion of 250 A/mm at H-gamma. Intensity traces of 20 selected spectra, made on the Kodak IIa-O plates, were made. The results were corrected for all instrumental effects and the interstellar extinction. The relative emission lines intensities have been obtained from the tracings after normalization to H-beta = 100. The spectra were typical for the quiet symbiotic star. So, all changes in the spectrum were caused by geometrical effects (eclipse). A preliminary analysis of the obtained spectra is presented. (Auth.)

    The dyeing of acrylic fabrics using C.I. Astrazon Basic Red 5BL 200% has been studied with both conventional and ultrasonic techniques. The effect of dye concentration, dye bath pH, ultrasonic power, dyeing time and temperature were studied and the resulting shades obtained by dyeing with both techniques were compared. Colour strength values obtained were found to be higher with ultrasonic than with conventional heating. The results of fastness properties of the dyed fabrics were studied. X-ray and Scanning Electron Microscope SEM were carried out on dyed samples using both methods of dyeing to find out an explanation for the better dyeability of acrylic fabrics with (US) method. Dyeing kinetics of acrylic fabrics using C.I. Astrazon Basic Red 5BL 200% using conventional and ultrasonic conditions were compared. The time/dye-uptake isotherms are revealing the enhanced dye-uptake in the second phase of dyeing. The values of dyeing rate constant, half-time of dyeing and standard affinity and ultrasonic efficiency have been calculated and discussed.

    Full Text Available Partindo das contribuições freudianas sobre as relações do ciúme com a projeção e a homossexualidade, propõe-se no presente artigo uma retomada do papel do masoquismo primário e da identificação feminina como elementos definidores do ciúme masculino patológico. As condições originárias de constituição do psiquismo, vistas sob o ângulo da Teoria da Sedução Generalizada, proposta por Jean Laplanche, são relacionadas tanto ao masoquismo primário quanto à identificação feminina. A situação assimétrica entre o adulto, portador de uma sexualidade inconsciente, e a criança, destituída de recursos psíquicos para lidar com as mensagens sexuais do adulto, caracteriza, segundo esse autor, a situação antropológica fundamental.

    This study was designed as ''proof of concept'' for a drug development model utilising multi-tracer serial small animal PET imaging to characterise tumour responses to molecularly targeted therapy. Mice bearing subcutaneous A431 human squamous carcinoma xenografts (n=6-8) were treated with the pan-Erb-B inhibitor CI-1033 or vehicle and imaged serially (days 0, 3 and 6 or 7) with [ 18 F]fluorodeoxyglucose, [ 18 F]fluoro-L-thymidine, [ 18 F]fluoro-azoazomycinarabinoside or [ 18 F]fluoromisonidazole. Separate cohorts (n=3) were treated identically and tumours were assessed ex vivo for markers of glucose metabolism, proliferation and hypoxia. During the study period, mean uptake of all PET tracers generally increased for control tumours compared to baseline. In contrast, tracer uptake into CI-1033-treated tumours decreased by 20-60% during treatment. Expression of the glucose transporter Glut-1 and cell cycle markers was unchanged or increased in control tumours and generally decreased with CI-1033 treatment, compared to baseline. Thymidine kinase activity was reduced in all tumours compared to baseline at day 3 but was sevenfold higher in control versus CI-1033-treated tumours by day 6 of treatment. Uptake of the hypoxia marker pimonidazole was stable in control tumours but was severely reduced following 7 days of CI-1033 treatment. CI-1033 treatment significantly affects tumour metabolism, proliferation and hypoxia as determined by PET. The PET findings correlated well with ex vivo biomarkers for each of the cellular processes studied. These results confirm the utility of small animal PET for evaluation of the effectiveness of molecularly targeted therapies and simultaneously definition of specific cellular processes involved in the therapeutic response.

    Full Text Available Temat ochrony przeciwpowodziowej, w tym polderów, jest zwykle podnoszony przy okazji każdej większej powodzi i po pewnym czasie, gdy zastosowano już doraźne środki naprawcze, dyskusja cichnie. Poldery jako obiekty hydrotechniczne, mające za zadanie przejąć szczyt fali powodziowej, wzbudzają wiele przeciwstawnych emocji. Z jednej strony uważa się, że są to obiekty, które mogą skutecznie uzupełniać system ochrony przeciwpowodziowej i pozytywnie wpływać na środowisko przyrodnicze. Z drugiej strony wysokie koszty, niska efektywność i wiele innych elementów sprawiają, że nie jest to popularna forma ochrony przed powodzią. W części obliczeniowej pracy skupiono się na nieistniejącym polderze w Stężycy o całkowitej pojemności równej około 24 mln m3. Model odcinka Wisły z uwzględnieniem istnienia polderu wykonano w programie HEC-RAS. Obliczenia dotyczyły szybkości napełniania tego zbiornika przy trzech różnych wariantach przepływu nieustalonego i przy różnych długościach przelewu na wlocie do polderu. Symulacje wykazały, że w krytycznym przypadku niezbędny byłby wlot o długości ok. 400 m, aby w całości napełnić polder podczas trwania wezbrania. W drugiej części pracy podjęto dyskusję na temat pozytywnych i negatywnych aspektów budowy polderów.

Próby podejmowane przez Parlament Europejski w celu poprawy sytuacji mniejszości narodowych i etnicznych w Unii Europejskiej mogą być odpowiednim impulsem do wstępnych refleksji. Pomimo wielu starań Unii Europejskiej oraz wykorzystania funduszy unijnych sytuacja mniejszości romskiej nie uległa dużej poprawie. Głównymi przyczynami są niedostateczne działania ze strony Unii Europejskiej, korupcja urzędników, a także brak zainteresowania społecznością romską państw członkowskich. Dotychczas podjęte działania nie przyniosły zamierzonych rezultatów, dlatego konieczne jest poświęcenie większej uwagi tej kwestii.

    Full Text Available Tak zwana teoria wartości opartej na pracy (odtąd LTV, niegdyś powód do dumy całego środowiska marksistowskiego, stawała się z upływem lat przedmiotem jego zakłopotania. Jej odrzucenie w ramach tradycji lewicowej, zarówno przez część filozofów, jak i ekonomistów, wpisuje się w szersze zjawisko zwane „kryzysem marksizmu”. Wówczas to filozoficzna część środowiska marksistowskiego, chcąc uwolnić marksizm od wad „ekonomizmu”, odcięła go także od zalet mogących płynąć z przyjęcia perspektywy ekonomii teoretycznej. Natomiast część ekonomiczna przywołanego środowiska, chcąc uwolnić ekonomię marksistowską od niedociągnięć tkwiących w LTV, odcięła ją także od szczególnego statusu przypisywanego w tej tradycji intelektualnej pojęciu pracy. Chociaż uniewinniono później LTV od zarzutu o domniemaną logiczną sprzeczność, to jedynie po to, aby skazać ją następnie na zapomnienie za jej rzekomą zbyteczność. W niniejszym artykule omówiona zostanie specyfika Marksowskiej wersji LTV. We wstępie podane zostaną cztery jakościowe założenia, które, zdaniem autora, przesądzają o charakterze Marksowskiej wersji LTV, W pierwszej części zarysowane zostanie miejsce LTV w historii myśli ekonomicznej. Druga część dotyczyć będzie losów Marksowskiej wersji LTV w ramach samej tradycji marksistowskiej. W trzeciej części omówiony zostanie problem wartości i jej pomiaru. Czwarta część zostanie poświęcona analizie problemu pracy i wyboru jednostki jej pomiaru, a także próbie zrekonstruowania Marksowskiej teorii reprodukcji pracowników za pomocą pracy. W części piątej podjęta zostanie kwestia tego, jak interpretuje się współcześnie status metodologiczny marksowskiej wersji LTV. Artykuł kończy podsumowanie.

  20. Combination of rapamycin, CI-1040, and 17-AAG inhibits metastatic capacity of prostate cancer via Slug inhibition.

    Directory of Open Access Journals (Sweden)

    Guanxiong Ding

    Full Text Available Though prostate cancer (PCa has slow progression, the hormone refractory (HRCP and metastatic entities are substantially lethal and lack effective treatments. Transcription factor Slug is critical in regulating metastases of various tumors including PCa. Here we studied targeted therapy against Slug using combination of 3 drugs targeting 3 pathways respectively converging via Slug and further regulating PCa metastasis. Using in vitro assays we confirmed that Slug up-regulation incurred inhibition of E-cadherin that was anti-metastatic, and inhibited Bim-regulated cell apoptosis in PCa. Upstream PTEN/Akt, mTOR, Erk, and AR/Hsp90 pathways were responsible for Slug up-regulation and each of these could be targeted by rapamycin, CI-1040, and 17-AAG respectively. In 4 PCa cell lines with different traits in terms of PTEN loss and androgen sensitivity we tested the efficacy of mono- and combined therapy with the drugs. We found that metastatic capacity of the cells was maximally inhibited only when all 3 drugs were combined, due to the crosstalk between the pathways. 17-AAG decreases Slug expression via blockade of HSP90-dependent AR stability. Combination of rapamycin and CI-1040 diminishes invasiveness more potently in PCa cells that are androgen insensitive and with PTEN loss. Slug inhibited Bim-mediated apoptosis that could be rescued by mTOR/Erk/HSP90 inhibitors. Using mouse models for circulating PCa DNA quantification, we found that combination of mTOR/Erk/HSP90 inhibitors reduced circulating PCa cells in vivo significantly more potently than combination of 2 or monotherapy. Conclusively, combination of mTOR/Erk/Hsp90 inhibits metastatic capacity of prostate cancer via Slug inhibition.

Os registros analisados foram coletados na Escola de Aplicação da Feusp, no ano de 2001, durante o acompanhamento de três aulas de Ciências: o problema do submarino, o problema do barquinho e o problema da pressão. O artigo procura mostrar um panorama de como aparecem os registros realizados pelos alunos, após uma aula de Ciências em que eles são levados a resolver situações problemáticas por meio da experimentação, argumentar e escrever sobre os fenômenos físicos. Durante a análise, levou-se em consideração os tipos de textos que os alunos escrevem, o uso da primeira pessoa, o uso de verbos de ação, o respeito à ordem cronológica dos eventos e quais os tipos de explicações os alunos atribuem aos fenômenos trabalhados.This article analyzed the written records of Third Grade students of Elementary School at Escola de Aplicação, Universidade de São Paulo, gathered during the Science classes of the 2001 school year, in which activities about physical understanding were used.

    Full Text Available The equivalency canard Efraim Zuroff's text, originally published in Haaretz magazine, is a review of Timothy Snyder's Bloodlands. Snyder distinguishes six main mass murders commited by Nazi Germany and Soviet Union during the period of the Third Reich's existence. In Zuroff's opinion there are some significant differences between these tragedies. Dubious comparisons proposed by Snyder made the Holocaust most affected. Describing the Shoah as one of the six equally horryfying mass murders, the author ignores its ideological roots. Roots that sentenced to death all Jews  - regardless of their political views, religious practicies or the level of identification with Jewish community. Moreover Snyder takes no notice of the georaphical scope of the Holocaust. He also does not notice the fact, that the Nazis effectively managed to make so many Europeans their accomplices, who actively supported the Shoah.   Fałszywy znak równości Tekst Efraima Zuroffa, który pierwotnie ukazał się w piśmie Haaretz, to recenzja książki Skrwawione ziemie Timothy Snydera. Snyder wyróżnia sześć głównych masowych mordów popełnionych przez Niemcy i Związek Radziecki w okresie, który odpowiada istnieniu Trzeciej Rzeszy. Istnieją jednak, zdaniem Zuroffa, znaczące różnice między tymi tragediami. Na wątpliwych porównaniach, które proponuje Snyder, najbardziej „ucierpiał” Holokaust. Opisując Shoah jako jeden z sześciu równie straszliwych, masowych mordów, autor pomija jego ideologiczne korzenie, które sprawiały, że na śmierć skazany był każdy bez wyjątku Żyd, niezależnie od jego poglądów politycznych, praktyk religijnych czy stopnia identyfikacji z żydowską wspólnotą. Ponadto Snyder ignoruje ogromny zasięg geograficzny Holokaustu. Nie zauważa także skuteczności, z jaką naziści potrafili uczynić swoimi wspólnikami tak wielu Europejczyków, którzy w konsekwencji aktywnie wspomagali Shoah.

  4. Improving Vegetable Oil Fueled CI Engine Characteristics Through Diethyl Ether Blending

    In this research, the flow and ignition properties of vegetable oil (VO) are improved by blending it with diethyl ether (DEE). DEE, synthesized from ethanol, has lower viscosity than diesel and VO. When DEE is blended with VO, the resultant DEEVO mixtures have favorable properties for compression ignition (CI) engine operation. As such, DEEVO20 (20% DEE + 80% VO) and DEEVO40 (40% DEE + 60% VO) were initially considered in the current study. The viscosity of VO is 32.4*10−6 m2/s; the viscosity is reduced with the increase of DEE in VO. In this study, our blends were limited to a maximum of 40% DEE in VO. The viscosity of DEEVO40 is 2.1*10−6 m2/s, which is comparable to that of diesel (2.3*10−6 m2/s). The lower boiling point and flash point of DEE improves the fuel spray and evaporation for DEEVO mixtures. In addition to the improvement in physical properties, the ignition quality of DEEVO mixtures is also improved, as DEE is a high cetane fuel (DCN = 139). The ignition characteristics of DEEVO mixtures were studied in an ignition quality tester (IQT). There is an evident reduction in ignition delay time (IDT) for DEEVO mixtures compared to VO. The IDT of VO (4.5 ms), DEEVO20 (3.2 ms) and DEEVO40 (2.7 ms) was measured in IQT. Accordingly, the derived cetane number (DCN) of DEEVO mixtures increased with the increase in proportion of DEE. The reported mixtures were also tested in a single cylinder CI engine. The start of combustion (SOC) was advanced for DEEVO20 and DEEVO40 compared to diesel, which is attributed to the high DCN of DEEVO mixtures. On the other hand, the peak heat release rate decreased for DEEVO mixtures compared to diesel. Gaseous emissions such as nitrogen oxide (NOX), total hydrocarbon (THC) and smoke were reduced for DEEVO mixtures compared to diesel. The physical and ignition properties of VO are improved by the addition of DEE, and thus, the need for the trans-esterification process is averted. Furthermore, this blending strategy is simpler

    Full Text Available Branding Greenland as a form of expression of national identity? In the times of globalisation there is a tendency for countries to differentiate from others. More and more governments decide to launch professional nation branding campaigns in order to communicate to a broad public what a particular country has to offer as well as what values and images it wants to be associated with. Greenland is an example of a country that after a long period of colonisation and establishing self-government, in 2009 began to redefine its identity and reveal it to the world. A branding campaign has been implemented to communicate a newly defined image of Greenland. This campaign has been carried out using mainly social media and the tools that the Internet has to offer. The aim of this paper is to explore the concept of nation branding and to define the relation between nation branding and national identity. The purpose is also to analyse what images of Greenland as a brand are presented by “Pioneering nation” campaign.   Branding Grenlandii formą ekspresji tożsamości narodowej?

Grenlandia to przykład państwa, które po długim okresie skolonizowania i po uzyskaniu autonomii w 2009 roku, zaczęło na nowo definiować swoją tożsamość i komunikować ją światu. W tym celu wdrożona została kampania, która wykorzystywała głównie media społecznościowe oraz inne narzędzia, które zapewnia internet. Celem niniejszego artykułu jest zbadanie zależności między brandingiem narodowym a tożsamością narodową, jak też analiza obrazu Grenlandii jako marki konstruowanej w kampanii „Pioneering nation”.

    Full Text Available The standard of living, quality of life, and development of a nation depend on its per capita energy consumption. Global energy supply that mainly depends on fossil fuel is decreasing day by day. It is estimated that the energy demand will be increased five times by the year 2021 from present scenario. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Pyrolysis is one of the promising alternative fuel technologies which produces valuable oil, char, and gas product from organic waste. Early investigations report that tire pyrolysis oil extracted from vacuum pyrolysis method seemed to have properties similar to diesel fuel. The main concern of this paper is to produce and improve the properties of crude tire pyrolysis oil by desulfurizing, distilling, and utilizing it with diesel in CI engine to analyze the efficiency for various compositions.

    Hylleraas-CI is a superposition-of-configurations method in which each configuration is constructed from a Slater-type orbital (STO) product to which is appended (linearly) at most one interelectron distance r{sub ij}. Computations of the kinetic energy for atoms by this method have been difficult due to the lack of formulas expressing these matrix elements for general angular momentum in terms of overlap and potential-energy integrals. It is shown here that a strategic application of angular-momentum theory, including the use of vector spherical harmonics, enables the reduction of all atomic kinetic-energy integrals to overlap and potential-energy matrix elements. The new formulas are validated by showing that they yield correct results for a large number of integrals published by other investigators.

    Full Text Available W ostatnich latach problem eutrofizacji stał się powszechny nie tylko w wodach stojących ale także w płynących. Budzi on spore zainteresowanie zwłaszcza gdy zaczyna dotyczyć wód przeznaczonych do zaopatrzenia ludzi w wodę do spożycia. Zbiornik Dobczycki o którym traktuje artykuł jest właśnie takim rezerwuarem. Tu ujmowana jest woda dla mieszkańców Krakowa. W literaturze spotyka się stwierdzenia, że wody zbiornika zawsze były podatne na eutrofizację ze względu na ładunki biogenów które są wnoszone do niego przez Rabę. Problem oceny stopnia eutrofizacji Zbiornika Dobczyckiego został więc podjęty nie tyle ze względów poznawczych, co utylitarnych. Wymagał rzetelnej i szczegółowej analizy danych pomiarowych pochodzących z monitoringu. Do oceny zjawiska eutrofizacji wykorzystano integralny wskaźnik troficzności ITS. Jest on jednym z coraz powszechniej stosowanych obecnie zagregowanych wskaźników. Dostrzeżono że graniczne wartości pojedynczych parametrów niekoniecznie odzwierciedlają stan trofii i uprawniają do wnioskowania o zjawisku eutrofizacji. Zastosowanie wskaźnika ITS wiąże się z wykorzystaniem parametrów takich jak pH i nasycenie wody tlenem, które odzwierciedlają bilans gazowy w wodach, zmieniający się wraz ze zmianą bilansu procesów produkcji i rozkładu materii organicznej. Nie wymaga on więc szczegółowych oznaczeń monitoringowych, przez co może być wykorzystywany jako uniwersalny sposób oceny trofii. W artykule uzasadniono wybór wskaźnika ITS jako metody oceny trofii na podstawie analizy statystycznej danych monitoringu Zbiornika pochodzących z okresu wieloletniego. Uwiarygodniło to ocenę i pozwoliło dostrzec pewne prawidłowości procesu oraz jego dynamikę. Na jej podstawie możliwa jest prognoza prawdopodobnego scenariusza dalszego rozwoju zjawiska.

    Full Text Available Wprowadzone w 1999 r. gimnazja miały służyć wyrównywaniu szans edukacyjnych dzieci z terenów wiejskich. Jednym z założeń reformy było stworzenie dużych, samodzielnych i dobrze wyposażonych gimnazjów, w których wspólnie uczyliby się absolwenci wszystkich szkół podstawowych z terenu gminy. Po kilkunastu latach funkcjonowania gimnazja pod względem organizacyjnym bardzo się zróżnicowały – w niektórych gminach, zgodnie z założeniami reformatorów, ciągle funkcjonują duże i samodzielne gimnazja, jednak w części gmin bardzo małe gimnazja działają w zespole ze szkołą podstawową, gdzie uczniowie przez dziewięć lat nie zmieniają kolegów, nauczycieli i środowiska. Na podstawie ośmiu studiów przypadku gmin wiejskich pokazano w artykule proces kształtowania sieci gimnazjów w pierwszych latach reformy systemu szkolnego. Próbowano zrozumieć, jakie czynniki zadecydowały o wytworzeniu się tych dwóch modeli gimnazjum. Przedstawione studia przypadku pokazują, że sieć szkolna jest nie tyle wynikiem realizacji planów tworzenia sieci szkolnej przez władze lokalne, ile raczej wynikiem gry pomiędzy lokalnymi władzami a lokalnymi społecznościami.

  3. The functional significance of cortical reorganization and the parallel development of CI therapy

    Full Text Available For the 19th and the better part of the 20th centuries two correlative beliefs were strongly held by almost all neuroscientists and practitioners in the field of neurorehabilitation. The first was that after maturity the adult CNS was hardwired and fixed, and second that in the chronic phase after CNS injury no substantial recovery of function could take place no matter what intervention was employed. However, in the last part of the 20th century evidence began to accumulate that neither belief was correct. First, in the 1960s and 1970s, in research with primates given a surgical abolition of somatic sensation from a single forelimb, which rendered the extremity useless, it was found that behavioral techniques could convert the limb into an extremity that could be used extensively. Beginning in the late 1980s, the techniques employed with deafferented monkeys were translated into a rehabilitation treatment, termed Constraint Induced Movement therapy or CI therapy, for substantially improving the motor deficit of the upper and lower extremities in the chronic phase after stroke. CI therapy has been applied successfully to other types of damage to the CNS such as traumatic brain injury, cerebral palsy, multiple sclerosis, and spinal cord injury, and it has also been used to improve function in focal hand dystonia and for aphasia after stroke. As this work was proceeding, it was being shown during the 1980s and 1990s that sustained modulation of afferent input could alter the structure of the CNS and that this topographic reorganization could have relevance to the function of the individual. The alteration in these once fundamental beliefs has given rise to important recent developments in neuroscience and neurorehabilitation and holds promise for further increasing our understanding of CNS function and extending the boundaries of what is possible in neurorehabilitation.

    Science outreach and engagement are crucial core objectives of the Lagos Ciência Viva Science Centre (CCVL). By engaging audiences in the real world a link is made between their science centre experience and the environment in which they live. Therefore, it has been an option of the CCVL to offer geological outdoor activities, both in the natural environment and urban context. Dinosaurs are an appealing science subject for both students and tourists. Thus, the CCVL has a long tradition in organizing and guiding field trips to two dinosaur track sites - Salema and Santa beaches (Vila do Bispo, southwest Algarve). These sites, both from the Lower Cretaceous reveal at least two types of tracks - theropod and iguanodontian footprints. Often in combination with the paleontology field trips, the CCVL also offers different geological field trips both for formal (school) and informal (tourism) education. This allows students and tourists to be introduced to dinosaur paleobiology and ichnology and to the structural geology and stratigraphy of the area. Our science outreach is being further developed by contractual agreement with a regional tour operator, in which the CCVL is responsible for the scientific content and guidance of the visits. Aiming at an urban context, the CCVL produced three Urban Geology and Paleontology Guide Books for three Algarve cities (Lagos, Faro and Tavira), which can be acquired in the three Ciência Viva Science Centres shops as well as in the tourist information offices serving this way as a basis for guided urban tours also offered by the CCVL. Based on our experience, we review and contextualise these geoscience activities and their potential for science outreach, communication and tourism. We discuss and propose a classification of different possibilities in geoscience communication and outreach based on three vertices: Science, Heritage and Geotourism. Some particularities of these visits, such as the merge between geosciences and other

As they do not always act rationally, have a tendency to overreact and cannot remove all emo-tional components from their decision-making process, it may be difficult to explain their behavior and investment decisions during the crisis, especially those concerning the sale of shares. The huge drop in share prices on world stock markets was visible in the early stages of the crisis, but it probably was not justified by actual deterioration of the financial situation of listed companies. The Global Financial Crisis triggered a wave of panic selling of shares on the Warsaw Stock Exchange (WSE. As the fluctuations in share prices do not always reflect the real economic situation of the companies, it is worth to examine whether the financial standing of companies listed on WSE actually deteriorated and whether the number of companies facing bankruptcy grew during the 2007 Crisis. The main purpose of this article is to evalu-ate the influence of the recent financial crisis on the financial situation and performance of Polish listed companies. Eight multiple discriminant analysis models were utilized to evaluate the real changes in the financial situation of Polish listed companies during the crisis (years 2006-2011. The aforementioned models enable prediction of corporate bankruptcy and measurement of financial health of companies. Theoretically, the number of companies facing bankruptcy should increase in time of crisis. As many as 175 joint-stock companies listed on the regulated market of the WSE were covered by the study. Their financial data were extracted from the Notoria

    Recent studies of comets and cometary dust have confirmed the presence of biologically relevant organic molecules along with clay minerals and water ice. It is also now well established by deuterium/hydrogen ratios that the CI1 carbonaceous meteorites contain indigenous extraterrestrial water. The evidence of extensive aqueous alteration of the minerals in these meteorites led to the hypothesis that water-bearing asteroids or comets represent the parent bodies of the CI1 (and perhaps CM2) carbonaceous meteorites. These meteorites have also been shown to possess a diverse array of complex organics and chiral and morphological biomarkers. Stable isotope studies by numerous independent investigators have conclusively established that the complex organics found in these meteorites are both indigenous and extraterrestrial in nature. Although the origin of these organics is still unknown, some researchers have suggested that they originated by unknown abiotic mechanisms and may have played a role in the delivery of chiral biomolecules and the origin of life on Early Earth. In this paper we review these results and investigate the thermal history of comets. We show that permanent as well as transient domains of liquid water can be maintained on a comet under a plausible set of assumptions. With each perihelion passage of a comet volatiles are preferentially released, and during millions of such passages the comet could shed crustal debris that may survive transit through the Earth's atmosphere as a carbonaceous meteorite. We review the current state of knowledge of comets and carbonaceous meteorites. We also present the results of recent studies on the long-term viability of terrestrial ice-microbiota encased in ancient glacial ice and permafrost. We suggest that the conditions which have been observed to prevail on many comets do not preclude either survivability (or even the active metabolism and growth) of many types of eukaryotic and prokaryotic microbial

    Full Text Available This paper presents the life cycle impact assessment (LCIA results of biodiesel produced from rapeseed oil. The functional unit (FU is defined as 3750 km of distance traveled by a truck fuelled with biodiesel. The reference flow is 1000 kg of biodiesel. The LCIA method used in the study is the ReCiPe method. At midpoint level the ReCiPe method addresses environmental issues within 18 impact categories. Most of these midpoint impact categories are further converted and aggregated into 3 endpoint categories (damage to human health, damage to ecosystem diversity, damage to mineral resource availability. The total impact of biodiesel’s life cycle was estimated at 540 Pt/FU. The damage to ecosystem diversity (1.48E-04 species•year/FU, the damage to human health (7.48E-03 DALY/FU and the damage to mineral resource availability (8.11E+03 US$/FU are responsible for 63%, 27% and 10% of the total negative impact in the life cycle of biodiesel, respectively. The results have revealed that only 4 impact categories are responsible for most of the impacts within the specific endpoint categories. These are impacts associated with global warming (3000 kg CO2 ekv./FU, particulate matter formation (12.4 kg PM ekv./FU, agricultural land occupation (6710 m2a./FU and fossil fuel depletion (21168 MJ/FU. Greenhouse gases emitted in the life cycle of biodiesel (mainly N2O, CO2 are responsibly for 56% of the damage caused to human health and for 16% of the damage caused to ecosystem diversity. Airborne emissions which contribute to particulate matter formation (NOx, NH3, PM, SO2 are responsible for 43% of the damage caused to human health. Agricultural land occupation is responsible for 82% of the damage caused to the ecosystem diversity. Damage to mineral resource availability is almost entirely related to the depletion of fossil energy sources. The production chain of biodiesel and the combustion of biodiesel are responsible for 69% and 31% of the total impact of

Há processos e estruturas sociais, econômicos, políticos, culturais e outros que apenas começam a ser estudados. Além do que é local, nacional e regional, colocam-se problemas novos e fundamentais com a emergência da sociedade global. As fronteiras geográficas e históricas, culturais e civilizatórias parecem modificar-se em direções e formas surpreendentes. Indivíduo, grupo, classe, coletividade e povo são colocados diante de outros horizontes. O próprio pensamento científico é desafiado a elaborar conceitos e interpretações para dar conta de realidades pouco conhecidas.

    Full Text Available Incognito ergo sum: on indifference  The present article is an analysis of various types of indifference of non-Jewish inhabitants of Warsaw to the plight of Jewish Poles. The words of Krzysztof Dunin-Wąsowicz, a historian and “Żegota” activist, provide the vantage point for the analysis: Dunin-Wąsowicz claimed that around 75 per cent of the inhabitants of Warsaw “were indifferent to what was taking place behind the Ghetto wall”. Thomas Kuhne hypothesised that it was Germans’ indifference to the Jewish – not hatred – that legitimised the Nazi racial policies of the 1930s. This statement might also apply to the “75 per cent of the inhabitants of Warsaw”. The article is mainly based on articles published by ZWZ-AK, in particular Biuletyn Informacyjny.   Incognito ergo sum. O wytwarzaniu obojętności Autorka analizuje różne odcienie obojętności nieżydowskich mieszkańców Warszawy w latach czterdziestych wobec losu żydowskich Polaków. Punktem wyjścia jest zdanie Krzysztofa Dunin-Wąsowicza, historyka i działacza „Żegoty”, który stwierdził, że dla około 75 procent mieszkańców Warszawy „obojętne było to, co działo się poza murem getta”. Powołując się na tezę Thomasa Kuhnego, że to właśnie obojętność Niemców wobec Żydów – a nie nienawiść w stosunku do nich – „spowodowała masowe poparcie nazistowskiej polityki rasowej w latach trzydziestych”, autorka zastanawia się, czy „podobnej opinii nie można by sformułować pod adresem” 75 procent mieszkańców Warszawy. Materiał do analizy stanowią w znacznej mierze publikacje prasy ZWZ-AK, w tym przede wszystkim „Biuletyn Informacyjny”.

A secondary objective was to investigate fitting practices with the new processor. A comprehensive user satisfaction survey was conducted in a total of 186 subjects from 24 centres. In parallel, 23 professional questionnaires were collected from 11 centres. Overall, there was high satisfaction with the Naída CI processor from adults, children, experienced and new CI users as well as from professionals. The Naída CI processor was shown as being easy to use by all ages of recipients and by professionals. The majority of experienced CI users rated the Naída CI processor as being similar or better than their previous processor in all areas surveyed. The Naída CI was recommended by the professionals for fitting in all populations. Features like UltraZoom, ZoomControl and DuoPhone would not be fitted to very young children in contrast to adults. Positive ratings were obtained for ease of use, comfort and usefulness of the new functions and features of the Naída CI sound processor. Seventy-seven percent of the experienced CI users rated the new processor as being better than their previous sound processor from a general point of view. The survey also showed that fitting practices were influenced by the age of the user.

We evaluated BbCI treatment in elastase-induced pulmonary alterations. Methods.  C57BL/6 mice received intratracheal elastase (ELA group or saline (SAL group. One group of mice was treated with BbCI (days 1, 15, and 21 after elastase instillation, ELABC group. Controls received saline and BbCI (SALBC group. After 28 days, we evaluated respiratory mechanics, exhaled nitric oxide, and bronchoalveolar lavage fluid. In lung tissue we measured airspace enlargement, quantified neutrophils, TNFα-, MMP-9-, MMP-12-, TIMP-1-, iNOS-, and eNOS-positive cells, 8-iso-PGF2α, collagen, and elastic fibers in alveolar septa and airways. MUC-5-positive cells were quantified only in airways. Results. BbCI reduced elastase-induced changes in pulmonary mechanics, airspace enlargement and elastase-induced increases in total cells, and neutrophils in BALF. BbCI reduced macrophages and neutrophils positive cells in alveolar septa and neutrophils and TNFα-positive cells in airways. BbCI attenuated elastic and collagen fibers, MMP-9- and MMP-12-positive cells, and isoprostane and iNOS-positive cells in alveolar septa and airways. BbCI reduced MUC5ac-positive cells in airways. Conclusions. BbCI improved lung mechanics and reduced lung inflammation and airspace enlargement and increased oxidative stress levels induced by elastase. BbCI may have therapeutic potential in chronic obstructive pulmonary disease.

    The disposition of carbon-14 labeled CI-924 (I), 5,5'-[1,1-biphenyl]-2,5 diyl-bis(oxy)-bis-2,2'-dimethylpentanoic acid, was studied in beagle dogs and rats following single 10 mg/kg po doses. Serial plasma, urine and fecal samples were collected up to 168 hr and analyzed for total radioactivity. Peak 14 C plasma concentrations of 31 mcg/ml (dogs) and 66 mcg/ml (rats) were attained within 0.5 and 1.0 hr after dosing. The concentrations declined thereafter with estimated half life of 11 and 5 hr in rats and dogs, respectively. TLC radiochromatography revealed that I was the only component in circulating blood. Tissue distribution study in rats showed that the highest 14 C concentrations were found in plasma and liver with decreasing concentrations in lung, heart, kidney, skin, gonads, spleen, fat, muscle, adrenals, and brain. All tissue concentrations declined in parallel with plasma levels with half lives of 14-22 hr. Urinary and fecal excretion accounted for 1-3% and 92-96% of the dose, respectively. Balance study in bile duct cannulated rats showed that 90%, 1%, and 1% of the dose was excreted in bile, urine, and feces. Unchanged drug and varying amounts of its conjugate were the only products present in bile, urine or feces. These results indicate that I was completely absorbed and eliminated primarily by biliary excretion in the form of unchanged drug and its conjugate

    Xanthomonas axonopodis pv. ci tri (X ac) produces citrus canker disease in all citrus commercial species. The bacteria can be disseminated through vegetative propagation material in asymptomatic form. To optimize bacteria detection techniques applicable to asymptomatic citrus plant tissue routine analysis, ELISA, Immunofluorescence, Pcr, qRT P CR and host plant inoculation (bioassay) diagnostic techniques were compared. Tests were made from decimal dilutions between 108 uf6.ml-1 and 102 ufc.mL-1 using a pure culture of 49b strain.The detection level obtained was 1.8 x 102 ufc.mL-1 using Inmunofluorescence; 1.8x104 ufc.mL-1 with indirect ELISA, 1.8 x 103 ufc.mL-1 by means of PCR; 10 ufc.mL-1 through of qRT P CR and 230 ufc.mL-1 in sour orange inoculated plants. The experiment was repeated at least three times for each technique. Considering this result, and taking into account that sensitivity, practicity and cost, are important when a great number of plants need to be tested, the PCR and inoculation in host plants were those that met the best characteristics to be evaluated in asymptomatic plant material

    Ciência em Tela is an open access Brazilian science teacher education online journal that has been published twice a year since 2008 and which encourages the participation of professionals with different backgrounds and the submission of a variety of textual genres, besides research papers. Another feature is that the journal includes practicing schoolteachers not only as authors but also as reviewers, which not only provides those who submit contributions to the journal with an early feedback from their target audience but also helps empower schoolteachers by placing them in a discursive situation in which they are producers, as opposed to consumers, of discourses about science education. In this paper we describe the background to and main aspects of the journal's innovative editorial policy, which seeks to bridge gaps between communities and institutions linked to science education, as well as to discuss the challenges that arise from it, in particular, issues concerning internationalisation and funding, as well as the role of journals in times of colonisation and commodification of knowledge and of discourses.

  3. Sequence specificity of mutagenesis in the cI gene of bacteriophage lambda

    Studies of DNA base sequence alterations have shown that for every agent the mutagenic process is specific with respect to the types of base changes induced and the location of the changes in the DNA. Analysis of the types of mutations produced by mutagenic agents can provide insight into the mechanism of mutation and can suggest which DNA lesions may be involved in the actual mutagenic event. We have developed a system for the analysis of chemically induced base sequence alterations in the cI repressor gene of bacteriophage lambda using DNA sequencing techniques. To illustrate the utility of this type of analysis, we present the results obtained with ultraviolet light (UV). Irradiation of target DNA with UV alone, or UV followed by photoreactivating light (which removes dimers), produces mostly transitions at pyrimidine-pyrimidine sites. Conversely, irradiation with 313 nm light plus acetophenone (which produces only thymine dimers) produces mostly transversions at low efficiency. This and other evidence suggests that the actual premutagenic UV lesion in E. coli may not be pyrimidine-pyrimidine dimers, but rather pyr(6-4)pyo photoproducts

    Full Text Available An experimental analysis was done using a four-stroke, single cylinder, constant speed, water-cooled diesel engine, which was interfaced with Engine software. Performance and emission characteristics were evaluated for three non-edible vegetable oils, i.e. thumba, jojoba, neem oil, as well as jojoba methyl ester, to study the effect of injection pressure at 205, 220, 240 and 260 bar with a variation in injection timing at 23°bTDC and 28°bTDC. The performance of jojoba methyl ester improved with an increase in injection pressure. A maximum brake thermal efficiency of 29.72% was obtained with lower emissions compared to the other vegetable oils; this might be explained by low viscosity and better combustion. Further investigations were carried out with a new lubricant, SAE 5W-30, which improved the performance of the CI engine by 1.59%. All of the abovementioned investigations were fruitful and these results are expected to lead to substantial contributions in the development of a viable vegetable oil engine.

    The purpose of this metric and descriptive study was to identify the most productive authors and their collaborative research networks from articles published in Ciência & Saúde Coletiva between, 2005, and 2014. Authors meeting the cutoff criteria of at least 10 articles were considered the most productive authors. VOSviewer and Network Workbench technologies were applied for visual representations of collaborative research networks involving the most productive authors in the period. Initial analysis recovered 2511 distinct articles, with 8920 total authors with an average of 3.55 authors per article. Author analysis revealed 6288 distinct authors, 24 of these authors were identified as the most productive. These 24 authors generated 287 articles with an average of 4.31 authors per article, and represented 8 separate collaborative partnerships, the largest of which had 14 authors, indicating a significant degree of collaboration among these authors. This analysis provides a visual representation of networks of knowledge development in public health and demonstrates the usefulness of VOSviewer and Network Workbench technologies in future research.

    Full Text Available O Princípio da Euritmia é a afirmação de que os entes na natureza adoptam preferencialmente os comportamentos que preservam a sua integridade estrutural, estendendo a sua existência. Formulado no contexto de uma física não linear como alternativa ao paradigma de Niels Bohr, o Princípio surge como um dos desenvolvimentos fundamentais a partir das ideias de Louis de Broglie,  no âmbito da chamada  Escola de Lisboa. Reflecte-se sobre os conceitos de «Princípio», «Lei da Natureza» e «Emergência», tendo como objectivo estender o paradigma Eurítmico às Ciências Sociais e Humanas.  Propõe-se um processo dinâmico descrevendo as escolhas de um agente social de acordo com uma instanciação possível do Princípio. Usando uma simulação computacional desse processo, estudam-se os comportamentos  de  dois agentes sociais em interacção com o meio, entre si e com a totalidade do sistema que compõem. Define-se autómato não linear como conceito operativo fundamental no entendimento dos fenómenos de Emergência.

    Full Text Available Tekst stanowi fragment doktoratu Michaela Hardta Sztuka organizacji: źródła ontologii politycznej u Gilles'a Deleuze'a i Antonio Negriego. Autor analizuje w nim dialog, jaki Antonio Negri podejmuje z pismami Włodzimierza Lenina w okresie intensywnych walk społecznych i przekształceń składu klasowego we Włoszech w latach 1968-1973. Doszukując się w tym spotkaniu kluczowego zwrotu teoretycznego w myśli włoskiego marksisty, Hardt przekonuje, że to właśnie w tekstach rosyjskiego rewolucjonisty Negri odnalazł narzędzia pozwalające mu wyjść poza ograniczenia krytycznego marksizmu, uznającego klasę robotniczą przede wszystkim za obiekt wyzysku, przez uczynienie kwestii jej podmiotowości centralnym zagadnieniem i punktem wyjścia teorii.

    Full Text Available The development of information technology creates a new way of many aspects in life. Innovations in this technology affect toward business environment, especially banking, which makes the business run dynamically. All of the transaction of a bank will be processed easily with the presence of computer. A bank needs all of the changes in order to compete with competitors, and that includes changes in information technology. The more expanding and complex facilities applied in a bank, the more complex and diverse technology adopted by a bank. The implementation of technology information in banking is not simple, it needs a long term planning and maintenance system so that all of the technology information facilities could run well and give a significant impact. Technology monitoring or benchmarking is one of the options that is taken by a bank to maintain its existence in facing the tight competition. To create technology innovation in banking need a monitoring technology method that is named TW-CI. This method is used to fulfill business needs in facing a competition to get and choose information that can be used to support a decision, so that the innovation applied by a bank is efficient and finally give an added value and also create entanglement between a bank and its consumer.

  12. The Cuatro Ciénegas Basin in Coahuila, Mexico: An Astrobiological Precambrian Park

    2012-01-01

    Abstract The Cuatro Ciénegas Basin (CCB) is a rare oasis in the Chihuahuan Desert in the state of Coahuila, Mexico. It has a biological endemism similar to that of the Galapagos Islands, and its spring-fed ecosystems have very low nutrient content (nitrogen or phosphorous) and are dominated by diverse microbialites. Thus, it has proven to be a distinctive opportunity for the field of astrobiology, as the CCB can be seen as a proxy for an earlier time in Earth's history, in particular the late Precambrian, the biological frontier when prokaryotic life yielded at least partial dominance to eukaryotes and multicellular life. It is a kind of ecological time machine that provides abundant opportunities for collaborative investigations by geochemists, geologists, ecologists, and population biologists in the study of the evolutionary processes that structured Earth-based life, especially in the microbial realm. The CCB is an object of investigation for the identification of biosignatures of past and present biota that can be used in our search for extraterrestrial life. In this review, we summarize CCB research efforts that began with microbial ecology and population biology projects and have since been expanded into broader efforts that involve biogeochemistry, comparative genomics, and assessments of biosignatures. We also propose that, in the future, the CCB is sanctioned as a “Precambrian Park” for astrobiology.

    Centralized configuration management, including the use of automation tools such as Puppet, can greatly increase provisioning speed and efficiency when configuring new systems or making changes to existing systems, reduce duplication of work, and improve automated processes. However, centralized management also brings with it a level of inherent risk: a single change in just one file can quickly be pushed out to thousands of computers and, if that change is not properly and thoroughly tested and contains an error, could result in catastrophic damage to many services, potentially bringing an entire computer facility offline. Change management procedures can—and should—be formalized in order to prevent such accidents. However, like the configuration management process itself, if such procedures are not automated, they can be difficult to enforce strictly. Therefore, to reduce the risk of merging potentially harmful changes into our production Puppet environment, we have created an automated testing system, which includes the Jenkins CI tool, to manage our Puppet testing process. This system includes the proposed changes and runs Puppet on a pool of dozens of RedHat Enterprise Virtualization (RHEV) virtual machines (VMs) that replicate most of our important production services for the purpose of testing. This paper describes our automated test system and how it hooks into our production approval process for automatic acceptance testing. All pending changes that have been pushed to production must pass this validation process before they can be approved and merged into production.

    2015-06-01

    Full Text Available W tekstach Saula Friedländera problem indywidualnej pamięci Shoahstanowił jedną z głównych granic dla dyskursu. Punktem krytycznym jego refleksji nad pamięcią stała się kwestia społecznego myślenia zbawczego, które stanowiło reakcję obronną wobec katastrofy. Fenomen ten ujawnił się szczególnie wyraźnie w publicznej formie pamięci, która z jednej strony domagała się prostoty i jasnej interpretacji, jako że jej zadaniem było oswojenie niekoherencji, wyeliminowanie bólu oraz rozbudzenie nadziei u współczesnych; z drugiej strony indywidualna pamięć głęboka ocalałych – nie znająca zasad – nie godziła się na formę pamięci publicznej, mimo że nie była w stanie jej się oprzeć. Według Friedländera ekspansja pamięci publicznej i zanikanie pamięci indywidualnej sprawia, iż "pamięć Shoah prawdopodobnie nie ucieknie przed całkowitą rytualizacją"1. W swoich rozważaniach częstokroć zwracał on uwagę na to, że sztuka nie może przeciwdziałać oswajaniu grozy, ponieważ musi wyrażać indywidualną pamięć przeszłości w pewnych prostych formach. Oprócz tego problematyczny stał się fakt, że same kategorie sztuki po Holokauście zostały zawładnięte przez przemysł kulturowy i politykę, przez co problem pamięci stał się środkiem przetargowym dla innych celów. Nawiązując za Friedländerem do aktualnego impasu wobec różnych oswajających mechanizmów pamięci, spróbuję poddać pod rozwagę kwestię granic i możliwości w tworzeniu estetycznego pomostu między teraźniejszością a przeszłością.

  17. Bioinformatic analysis of the distribution of inorganic carbon transporters and prospective targets for bioengineering to increase Ci uptake by cyanobacteria.

    Cyanobacteria have evolved a carbon-concentrating mechanism (CCM) which has enabled them to inhabit diverse environments encompassing a range of inorganic carbon (Ci: [Formula: see text] and CO2) concentrations. Several uptake systems facilitate inorganic carbon accumulation in the cell, which can in turn be fixed by ribulose 1,5-bisphosphate carboxylase/oxygenase. Here we survey the distribution of genes encoding known Ci uptake systems in cyanobacterial genomes and, using a pfam- and gene context-based approach, identify in the marine (alpha) cyanobacteria a heretofore unrecognized number of putative counterparts to the well-known Ci transporters of beta cyanobacteria. In addition, our analysis shows that there is a huge repertoire of transport systems in cyanobacteria of unknown function, many with homology to characterized Ci transporters. These can be viewed as prospective targets for conversion into ancillary Ci transporters through bioengineering. Increasing intracellular Ci concentration coupled with efforts to increase carbon fixation will be beneficial for the downstream conversion of fixed carbon into value-added products including biofuels. In addition to CCM transporter homologs, we also survey the occurrence of rhodopsin homologs in cyanobacteria, including bacteriorhodopsin, a class of retinal-binding, light-activated proton pumps. Because they are light driven and because of the apparent ease of altering their ion selectivity, we use this as an example of re-purposing an endogenous transporter for the augmentation of Ci uptake by cyanobacteria and potentially chloroplasts.

  18. Identification and Validation of Novel Hedgehog-Responsive Enhancers Predicted by Computational Analysis of Ci/Gli Binding Site Density

    The Hedgehog (Hh) signaling pathway directs a multitude of cellular responses during embryogenesis and adult tissue homeostasis. Stimulation of the pathway results in activation of Hh target genes by the transcription factor Ci/Gli, which binds to specific motifs in genomic enhancers. In Drosophila, only a few enhancers (patched, decapentaplegic, wingless, stripe, knot, hairy, orthodenticle) have been shown by in vivo functional assays to depend on direct Ci/Gli regulation. All but one (orthodenticle) contain more than one Ci/Gli site, prompting us to directly test whether homotypic clustering of Ci/Gli binding sites is sufficient to define a Hh-regulated enhancer. We therefore developed a computational algorithm to identify Ci/Gli clusters that are enriched over random expectation, within a given region of the genome. Candidate genomic regions containing Ci/Gli clusters were functionally tested in chicken neural tube electroporation assays and in transgenic flies. Of the 22 Ci/Gli clusters tested, seven novel enhancers (and the previously known patched enhancer) were identified as Hh-responsive and Ci/Gli-dependent in one or both of these assays, including: Cuticular protein 100A (Cpr100A); invected (inv), which encodes an engrailed-related transcription factor expressed at the anterior/posterior wing disc boundary; roadkill (rdx), the fly homolog of vertebrate Spop; the segment polarity gene gooseberry (gsb); and two previously untested regions of the Hh receptor-encoding patched (ptc) gene. We conclude that homotypic Ci/Gli clustering is not sufficient information to ensure Hh-responsiveness; however, it can provide a clue for enhancer recognition within putative Hedgehog target gene loci.

    Very few studies focus on childhood abuse in developing countries and only a small fraction of such studies explicitly deal with abuse in a school environment. The purpose of this study was to estimate the prevalence of sexual, physical, and emotional abuse in a school environment in a developing country. Abuse history was collected using the International Society for the Prevention of Child Abuse and Neglect (ISPCAN) Child Abuse Screening Tool - Children's Institutional Version (ICAST-CI). Demographic variables were also collected. Student supportive measures were provided both during and after the survey. 6682 school attending adolescents in Thrissur, Kerala participated in this cross sectional self report study. One year and lifetime prevalence of physical (75.5%, 78.5%), emotional (84.5%, 85.7%) and sexual (21.0%, 23.8%) abuse was high. Abuse was considered to be present even if an individual item from these three categories was reported. Most abuse was reported as occurring 'sometimes' rather than 'many times'. More males than females reported being victims of abuse; figures for one-year prevalence were: physical abuse (83.4% vs. 61.7%), emotional abuse (89.5% vs. 75.7%), and sexual abuse (29.5% vs. 6.2%). Various factors significantly increase the likelihood of abuse-male gender, low socioeconomic status, regular use of alcohol and drugs by family member at home, and having other difficulties at school. Children tended to report abuse less frequently if they liked attending school and if they always felt safe at school. The results highlight the urgent need to address the issue of abuse in the school environment and minimize its impact. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This work presents results of a benchmark between calculated and experimental absorbed dose values for a typical product, in a 60 Co industrial irradiator, located at ININ, Mexico. The goal of this work is to reach a ± 10 % approximation between both values. ININ 60 Co industrial irradiator is a two level, two layer system with overlapping product configuration, 56 irradiation positions with an activity of around 250 k Ci. Calculated values were obtained by QAD-CGGP code. This code uses a point kernel technique, build-up factors fitting was done by geometrical progression and combinatorial geometry was used for 3 D system description. Main code modifications were related with source simulation by punctual sources and energy spectrum (16 energy groups) and anisotropic emission were also considered. Experimental data were obtained from routine dosimetry which was done with red acrylic pellets; they were irradiated together the product in predetermined positions, for 36 maximum and minimum absorbed dose values. Typical product was polypropylene Petri dish packages, apparent density 0.13 g/cm 3 . It was chosen because regular geometry (2 packages per full irradiator container) and enough amount for considering homogeneous loading inside irradiation chamber. Required minimum dose was 15 kGy. Results showed a 8% variation between calculated and experimental values for maximum absorbed dose (18.2 kGy vs 16.8 kGy) and 3 % variation for minimum absorbed dose (13.8 kGy vs 14.3 kGy); these results fixed with the original proposal.

Estes saberes, caracterizados pela mudança nos padrões de participação do professor na prática pedagógica, os quais não são construídos apenas durante o curso de formação inicial, mas sim ao longo da história de vida do educador. A partir dos conhecimentos de Paulo Freire e de Edgar Morin são sugeridos temas para possíveis práticas no ensino de ciências e de biologia. Dessa forma, uma educação em que o professor só deposita o conteúdo no aluno deve ser substituída por aquela que instiga a curiosidade, valoriza a opinião a sua opinião, considera seus sentimentos e promove a sua autonomia, ou seja, converte o educando em um agente transformador da sua própria realidade. Para isso, o professor precisa atuar com sentimentalidade, criticidade e autoridade, sem autoritarismo. Além disso, é papel do educador mostrar que não há conhecimento ileso ao erro ou a ilusão. Ele, também, precisa trabalhar o contexto local em relação a um conteúdo global. É um saber ensinar a condição do humano como unidade do universo e educar sobre a identidade terrena. Considerando, além disso, as incertezas dos acontecimentos e a ética humana. As discussões aqui apresentadas são sugestões para o desenvolvimento de práticas de ensino. No entanto, o professor deve elaborá-las de acordo com o seu ambiente de trabalho e seu público.

Since such concepts have an inherently trans-disciplinary character, the Information Science has been largely influenced by many disciplines, particularly the Cognitive Science. Regardless of this, it is observed that such concepts have not been properly discussed within the Information Science. To deal with this concern, it has been structured in the Escola de Ciência da Informação (ECI of the Universidade Federal de Minas Gerais (UFMG, a research group denoted “Cognitive Studies in Information Science”. This work aims to discuss the relationships between the Information Science and the Cognitive Science. In order to achieve this purpose, one formerly presents the major approaches within the Cognitive Science, contextualizing their aspects that mostly influence the Information Science, and then one discuss some perspectives for the future relationship of these two disciplines.O estudo da influência das Ciências Cognitivas na Ciência da Informação. A Ciência da Informação, que tem como objetos de estudo a informação e o conhecimento, discute-os sob vários pontos de vista, sendo um deles, o cognitivo. Observa-se que os conceitos não têm sido adequadamente discutidos à luz das Ciências Cognitivas, apesar da Ciência da Informação sofrer muitas influências daquela disciplina. Em função dessas questões, estruturou-se, na Escola de Ciência da Informação–ECI da Universidade Federal de Minas Gerais-UFMG, o Grupo de Pesquisa “Estudos Cognitivos em Ciência da Informação” – GECCI. Neste trabalho, marco inicial das discussões do grupo, tem-se o objetivo de discutir as relações da Ciência da Informação com as Ciências Cognitivas.

    all features which exclude you from the community and your positive “national identity.”   Naród kontra lewactwo. Polityczne kategoryzacje rzeczywistości w folklorze internetowym W znanym eseju Dziecięca choroba lewicowości w komunizmie Lenin, na określenie naiwnej jego zdaniem polityki zachodnich partii komunistycznych, używa pojęcia „lievizna”. Zwykle tłumaczy się je jako „lewicowość”, termin ten jednak nie oddaje pogardy dla zachodnich partii komunistycznych, z jaką Lenin się o nich wypowiadał. W języku polskim wyraz ten był także niekiedy przekładany jako „lewactwo”, po to by służył ośmieszaniu działań niezgodnych z nomenklaturą Polskiej Zjednoczonej Partii Robotniczej (przykładem może być ruch ‘68 na Zachodzie. Współcześnie określenie „lewactwo” najczęściej jest używane w dyskursie ruchów prawicowych, aby pokazać każdy niezgodny z nimi projekt jako „dziecinny”. Wyrazem tym określa się nie tylko ruchy lewicowe, ale także wszystkie inne, które nie wpisują się w dyskurs prawicy narodowej. W swoim artykule staram się pokazać, w jaki sposób wyraz ten służy jako fantazmatyczna bariera, granica definiująca tożsamość narodową. Za materiał badawczy posłużył mi folklor internetowy taki, jak: memy, komentarze pod artykułami i zdjęciami, krótkie filmiki na portalu YouTube, a także oferta internetowych sklepów z odzieżą i gadżetami patriotycznymi (oferta tych sklepów jest ściśle oparta na takiej folklorystycznej interpretacji wydarzeń ujmowanych jako ważne. Pojęcie „lewactwa” funkcjonuje jako bariera wyznaczająca tożsamość narodową oraz jako przestrzeń fantazji. Ideologiczna praca tego pojęcia pokazuje, w jaki sposób w opozycji do tej bariery definiuje się i wyznacza pozytywny zbiór tego, co jest postrzegane jako „narodowe”, oraz tego, co „narodem” nie jest. Ponadto „lewactwo” jest także używane jako ekran fantazji, na której projektuje się cechy

    Full Text Available Wstęp: Trening fizyczny uważany jest za czynnik wpływający na parametry antropometryczne i ciśnienie tęt‑ nicze. Twierdzi się, że osoby regularnie ćwiczące mają lepsze wskaźniki składu ciała oraz niższe wartości ciśnienia tętniczego krwi w porównaniu z osobami nieuprawiającymi sportu. Cel: Ocena wpływu regularnej rocznej aktywności fizycznej prowadzonej w szkole sportowej na skład ciała oraz wartości ciśnienia tętnicze‑ go u dzieci 14-letnich (II klasa gimnazjum. Materiał i metodyka: W badaniu wzięło udział 25 dzieci z gim‑ nazjum sportowego. Dzieci badano dwukrotnie w odstępie 12 miesięcy. Analizie poddano zmianę parame‑ trów antropometrycznych, składu ciała metodą impedancji bioelektrycznej oraz wartości ciśnienia krwi. Wyniki: W całej grupie zaobserwowano wzrost wartości centylowych ciśnienia skurczowego krwi (p < 0,05, przede wszystkim u chłopców. W zakresie ciśnienia rozkurczowego nie zanotowano istotnych różnic. Skład ciała zmienił się niekorzystnie u wszystkich badanych – wzrósł udział tłuszczu (13% vs 20%, p < 0,05, a przy‑ rost masy tłuszczowej był wyższy u dziewczynek (6% vs 3%, p < 0,05. Centyl BMI istotnie statystycznie wzrósł w grupie dziewczynek (37 vs 49, p < 0,05, u chłopców nie uległ zmianie. Wnioski: Aktywność fizyczna proponowana przez szkołę sportową nie poprawia stanu odżywienia 13–14-letnich dziewcząt i chłopców, u których obserwuje się istotne zwiększenie w organizmie zawartości tkanki tłuszczowej. Szkolna aktywność fizyczna nie powoduje obniżenia ciśnienia tętniczego wśród młodzieży w wieku 13–14 lat w odniesieniu do norm wiekowych. W zakresie ciśnienia skurczowego w grupie chłopców zaobserwowano nawet wyższe wartości centylowe.

    Ci-VSP contains a voltage-sensing domain (VSD) homologous to that of voltage-gated potassium channels. Using charge displacement ('gating' current) measurements we show that voltage-sensing movements of this VSD can occur within 1 ms in mammalian membranes. Our analysis lead to development of a genetically encodable fluorescent protein voltage sensor (VSFP) in which the fast, voltage-dependent conformational changes of the Ci-VSP voltage sensor are transduced to similarly fast fluorescence read-outs.

    Full Text Available O trabalho desenvolve as implicações da idéia de que quando uma teoria atinge um estágio abstrato de formalização, como é o caso de teorias físicas, da mecânica quântica, o significado de seus conceitos e proposições, objetivos para representação e inteligibilidade do mundo físico (realidade física em qualquer de suas acepções é obtido a partir da própria teoria. Em síntese, "é a própria que dita o significado de suas proposições", segundo Einstein e Heisenberg. Em seguida apresenta uma análise do significado de 'teoria formalizada' para o caso das ciências de conteúdo empírico como a física, concluindo que a acepção adotada não pode ser reduzida a um 'formalismo interpretado' nos moldes aceitos pelos elementos do Círculo de Viena. Aspectos dinâmicos das teorias são também discutidos. Finalmente, a partir das considerações acima, é introduzido o conceito de 'endo-referência' e discutidas as suas conexões com o conceito kantiano de sintético a priori.The paper develops epistemological implications of the idea that, when a theory is in state of abstract formalization (as to-day physical theory, quantum physics for instance is, the meaning of its concepts and propositions, which are aiming at the representation and intelligibility of the external physical world is however to be taken from within the theory itself. " It is the theory itself which dictates the physical significance of its propositions" in the words of Heisenberg and Einstein. It contains also the analysis of what is meant by " formalized theory" for a science with empirical content as physics and concludes that it cannot be reduced to a mere "interpreta formalism" in the sense of logical impiricism. Finaly it works on the sense of endoreference connctions with a kantian concept of a priori synthetic.

    Full Text Available A MADS-box gene, CiMADS9, was cloned from the male flowers of Carya illinoinensis by rapid amplification of cDNA ends. The gene was 1 077 bp with a 768 bp open reading frame encoding 255 amino acids. Multiple sequence comparisons revealed that CiMADS9 is a typical MIKC-type MADS-box gene with a MADS-box domain and a K semi-conserved region. Phylogenetic analysis indicated that CiMADS9 belongs to the AGL15 group of the MADS-box gene family. Quantitative reverse transcription polymerase chain reaction analysis indicated that the expression levels in reproductive organs (i.e., flowers and young fruits were considerably higher than in vegetative tissues (i.e., leaves and branches. The highest expression levels were observed in male flowers. An overexpression vector for CiMADS9 was constructed and the gene was inserted into the Arabidopsis thaliana genome. CiMADS9 expression was confirmed in all transgenic lines. Compared with wild-type plants, transgenic A. thaliana plants overexpressing CiMADS9 exhibited delayed flowering and an increased number of leaves.

    High-throughput screening generates large volumes of heterogeneous data that require a diverse set of computational tools for management, processing, and analysis. Building integrated, scalable, and robust computational workflows for such applications is challenging but highly valuable. Scientific data integration and pipelining facilitate standardized data processing, collaboration, and reuse of best practices. We describe how Jenkins-CI, an “off-the-shelf,” open-source, continuous integration system, is used to build pipelines for processing images and associated data from high-content screening (HCS). Jenkins-CI provides numerous plugins for standard compute tasks, and its design allows the quick integration of external scientific applications. Using Jenkins-CI, we integrated CellProfiler, an open-source image-processing platform, with various HCS utilities and a high-performance Linux cluster. The platform is web-accessible, facilitates access and sharing of high-performance compute resources, and automates previously cumbersome data and image-processing tasks. Imaging pipelines developed using the desktop CellProfiler client can be managed and shared through a centralized Jenkins-CI repository. Pipelines and managed data are annotated to facilitate collaboration and reuse. Limitations with Jenkins-CI (primarily around the user interface) were addressed through the selection of helper plugins from the Jenkins-CI community. PMID:27899692

  3. Oxidation of SO2 by stabilized Criegee intermediate (sCI radicals as a crucial source for atmospheric sulfuric acid concentrations

    2013-04-01

    Full Text Available The effect of increased reaction rates of stabilized Criegee intermediates (sCIs with SO2 to produce sulfuric acid is investigated using data from two different locations, SMEAR II, Hyytiälä, Finland, and Hohenpeissenberg, Germany. Results from MALTE, a zero-dimensional model, show that using previous values for the rate coefficients of sCI + SO2, the model underestimates gas phase H2SO4 by up to a factor of two when compared to measurements. Using the rate coefficients recently calculated by Mauldin et al. (2012 increases sulfuric acid by 30–40%. Increasing the rate coefficient for formaldehyde oxide (CH2OO with SO2 according to the values recommended by Welz et al. (2012 increases the H2SO4 yield by 3–6%. Taken together, these increases lead to the conclusion that, depending on their concentrations, the reaction of stabilized Criegee intermediates with SO2 could contribute as much as 33–46% to atmospheric sulfuric acid gas phase concentrations at ground level. Using the SMEAR II data, results from SOSA, a one-dimensional model, show that the contribution from sCI reactions to sulfuric acid production is most important in the canopy, where the concentrations of organic compounds are the highest, but can have significant effects on sulfuric acid concentrations up to 100 m. The recent findings that the reaction of sCI + SO2 is much faster than previously thought together with these results show that the inclusion of this new oxidation mechanism could be crucial in regional as well as global models.

  4. On the mechanical stability of the body-centered cubic phase and the emergence of a metastable cI16 phase in classical hard sphere solids

    The stability of the body-centered cubic (bcc) solid phase of classical hard spheres is of intrinsic interest and is also relevant to the development of perturbation theories for bcc solids of other model systems. Using canonical ensemble Monte Carlo, we simulated systems initialized in a perfect bcc lattice at various densities in the solid region. We observed that the systems rapidly evolved into one of four structures that then persisted for the duration of the simulation. Remarkably, one of these structures was identified as cI16, a cubic crystalline structure with 16 particles in the unit cell, which has recently been observed experimentally in lithium and sodium solids at high pressures. The other three structures do not exhibit crystalline order but are characterized by common patterns in the radial distribution function and bond-orientational order parameter distribution; we refer to them as bcc-di, with i ranging from 1 to 3. We found similar outcomes when employing any of the three single occupancy cell (SOC) restrictions commonly used in the literature. We also ran long constant-pressure simulations with box shape fluctuations initiated from bcc and cI16 initial configurations. At lower pressures, all the systems evolved to defective face-centered cubic (fcc) or hexagonal close-packed (hcp) structures. At higher pressures, most of the systems initiated as bcc evolved to cI16 with some evolving to defective fcc/hcp. High pressure systems initiated from cI16 remained in that structure. We computed the chemical potential of cI16 using the Einstein crystal reference method and found that it is higher than that of fcc by ˜0.5kT-2.5kT over the pressure range studied, with the difference increasing with pressure. We find that the undistorted bcc solid, even with constant-volume and SOC restrictions applied, is so mechanically unstable that it is unsuitable for consideration as a metastable phase or as a reference system for studying bcc phases of other systems

    DesignSafe is the web-based research platform of the Natural Hazards Engineering Research Infrastructure (NHERI) network that provides the computational tools needed to manage and analyze critical data for natural hazards research, with wind and storm surge related hazards being a primary focus. One of the simulation tools under DesignSafe is the Advanced Circulation (ADCIRC) model, a coastal ocean model used in storm surge analysis. ADCIRC is an unstructured, finite element model with high resolution capabilities for studying storm surge impacts, and has long been used in storm surge hind-casting and forecasting. In this talk, we will demonstrate the use of ADCIRC within the DesignSafe platform and its use for forecasting Hurricane Harvey. We will also demonstrate how to analyze, visualize and archive critical storm surge related data within DesignSafe.

    A magnetic adsorbent was synthesized by γ-aminopropyltriethoxysilane (APTES) modification of Fe(3)O(4) particles using a two-step process. Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and vibration sample magnetometry were used to characterize the obtained magnetic adsorbent. EDS and XPS showed that APTES polymer was successfully introduced onto the as-prepared Fe(3)O(4)/APTES particle surfaces. The saturation magnetization of the magnetic adsorbent was around 65 emu g(-1), which indicated that the dye can be removed fast and efficiently from aqueous solution with an external magnetic field. The maximum adsorption capacities of Fe(3)O(4)/APTES for C.I. Reactive Red 228 (RR 228) and Congo Red (CR) were 51.4 and 118.8 mg g(-1), respectively. The adsorption of C.I. Reactive Red 228 (RR 228) and Congo Red (CR) on Fe(3)O(4)/APTES particles corresponded well to the Langmuir model and the Freundlich model, respectively. The adsorption processes for RR 228 and CR followed the pseudo-second-order model. The Boyd's film-diffusion model showed that film diffusion also played a major role in the studied adsorption processes for both dyes. Thermodynamic study indicated that both of the adsorption processes of the two dyes are spontaneous exothermic.

    Full Text Available Wstęp: Przyprawy dodawane do żywności wzbogacają jej walory smakowe i zapachowe, niektóre z nich mogą także wydłużać jej czas przechowywania dzięki obecności związków o aktywności przeciwutleniającej. Cel: Celem pracy było zbadanie 28 przypraw dostępnych na rynku pod kątem całkowitej zawartości polifenoli i aktywności przeciwutleniającej. Metody: Do oceny całkowitej zawartości związków fenolowych zastosowano metodę Folina- Ciocalteau. Aktywność antyoksydacyjną ekstraktów oznaczono metodą z użyciem rodnika DPPH. Wyniki: Otrzymane wyniki wykazują, że większość analizowanych przypraw jest bogata w związki fenolowe i posiada wysoką aktywność antyoksydacyjną. Całkowita zawartość polifenoli w przyprawach oscylowała od 0,9 do 155,1 mg GAE/g z najniższą wartością odnotowaną dla sezamu i najwyższą dla cynamonu. Zdolność do wygaszania rodnika DPPH wyrażona w procentach była zróżnicowana i wahała się w zakresie od 4,1% dla sezamu do 94,9% dla goździków. Odnotowano umiarkowaną korelację (r=0,63, p<0,05 pomiędzy aktywnością antyoksydacyjną i zawartością polifenoli ogółem, co dowodzi, że związki fenolowe są ważnymi, antyoksydacyjnymi składnikami w badanych przyprawach. Wnioski: Prowadzone badania wykazują, że wiele przypraw może służyć jako naturalne konserwanty żywności i jednocześnie ma korzystny wpływ na nasze zdrowie.

    Full Text Available Astma jest chorobą, która charakteryzuje się odwracalną obturacją oskrzeli i postępującym spadkiem wskaźników wentylacji. Podstawową rolę w rozpoznawaniu astmy odgrywają badania spirometryczne z oznaczeniem podstawowych wartości natężonej pojemności życiowej (FVC i natężonej objętości wydechowej 1-sekundowej (FEV1 oraz wynikiem testu odwracalności obturacji oskrzeli. W monitorowaniu przebiegu astmy zaleca się oznaczanie wskaźnika określanego jako szczytowy przepływ wydechowy (PEF, jednak jego czułość jest mniejsza niż wskaźnika FEV1. Fundamentalną cechą astmy jest nadreaktywność oskrzeli, która wskazuje na większy stopień odpowiedzi oskrzeli osób chorych niż zdrowych. Nadreaktywność oskrzeli można określić, stosując wziewne testy prowokacyjne z bronchospastycznymi substancjami (histaminą, metacholiną, 5-AMP. U dzieci bardzo użyteczny jest test wysiłkowy, który charakteryzuje się dużą swoistością, ale małą czułością. Leczenie astmy poprawia jej kliniczny przebieg, jak również wskaźniki wentylacji, które pozwalają określić także stopień zaawansowania choroby. U chorych z przebudową oskrzeli nie obserwuje się wzrostu wskaźników wentylacji. Przebudowa oskrzeli powoduje nieodwracalną obturację i jest typowa dla chorych o ciężkim przebiegu tej choroby. W ciężkiej astmie ujemny wynik daje też test odwracalności obturacji oskrzeli, podobnie uzyskuje się niskie wartości PEF. Nadreaktywność oskrzeli jest użyteczna w procesie diagnozowania astmy. Jej wartość łączy się z zapaleniem alergicznym oskrzeli oraz wskaźnikami wentylacji. Leczenie poprawia przebieg kliniczny choroby i wskaźniki wentylacji, jednak nie wpływa na nadreaktywność oskrzeli.

    to the broader considerations related to uncertainty of the proposed method's measurements, due to the authors' awareness that this is the first prototype of such a device and, on the basis of this experience, another one will be built and tested. The observations and numerical analysis of the image formed on the screen by the passage of a laser beam through the free surface of the liquid-gas separation show that at low values of pressure difference, the bubble acts as a membrane shifting in the direction of lower pressure, in such way that the displacement is proportional to the pressure difference at both ends of the bubble. The proprietary method of numerical data processing presented in this article, based on analysis of the intensity of color change in a frame moving along a selected line outside of visual changes in the image of the laser beam after passing through the test structure, provided a tool to create first mathematical models to describe the observed changes (2),(3). Presented in this article method of measuring the difference between the free surface levels in two containers, and hence the measurement of hydrostatic pressure difference provides a new tool for laboratory measurements in the fields of science, which were previously unattainable.

    The treatment options for the hyperthyroidism of Graves' disease are antithyroid drugs, surgery and radioiodine, none of which is considered ideal, as they do not act directly on the etiopathogenesis of the disease. Radioiodine has been increasingly used as the treatment of choice because it is a safe and definitive therapy whose administration is very easy. Some authors prefer to administer higher doses in order to deliberately induce hypothyroidism, while others recommend lower doses that result in a lower incidence of hypothyroidism and a greater incidence of euthyroidism. There is no consensus for the optimal regimen of fixed doses to be used and this is the main focus of the present study, where doses of 10 and 15 mCi of {sup 131}I were compared. Among the 164 patients analyzed, 61 (37.2%) were submitted to 10 mCi and 103 (62.8%) to 15 mCi. In the longitudinal analysis it was observed that remission of the hyperthyroidism was statistically different in the sixth month (p < 0.001), being higher in the group that used the dose of 15 mCi, but similar in both groups at 12 and 24 months. It may be concluded that the administration of fixed doses of 10 and 15 mCi of {sup 131}I brought about a similar remission of the hyperthyroidism after 12 months of treatment. Moreover, the remission rate of the hyperthyroidism had no association with age, sex or previous therapy with antithyroid drugs. (author)

    Full Text Available "Aftermath", after-Gross and the fans of Polishness Aftermath was released in the late 2012. Its director, Władysław Pasikowski, had previously been famous for his violent action films with strong male protagonists. He has also written some of the most sexist dialogues in the history of Polish cinema, as well as a number of lines, often obscene, which have become catchphrases and slogans present every day in the pop culture. His latest film, however, tackles a completely different issue – this thriller-cum-western tells a story that is decidedly contemporary, but nevertheless inspired by the events that took place in Jedwabne (described by Jan Tomasz Gross in his book Neighbors. Aftermath does not attempt to provide a reconstruction of the events that took place “on the margins of the Holocaust” (including Jedwabne. However, it clearly hints at the issue of the Polish contribution to the extermination of Jews and the impact of the conspiracy of silence having been broken. The film gave rise to a heated debate, which rippled through the Polish media for as long as two months after its release. This article is an attempt to analyse and interpret the words and ideas that appeared in the debate.   „Pokłosie”, poGrossie i kibice polskości Wraz z końcem 2012 roku odbyła się premiera filmu fabularnego Pokłosie w reżyserii Władysława Pasikowskiego.

    The software application FOX ('Fitting to Outcome eXpert') is an intelligent agent to assist in the programing of cochlear implant (CI) processors. The current version utilizes a mixture of deterministic and probabilistic logic which is able to improve over time through a learning effect. This study aimed at assessing whether this learning capacity yields measurable improvements in speech understanding. A retrospective study was performed on 25 consecutive CI recipients with a median CI use experience of 10 years who came for their annual CI follow-up fitting session. All subjects were assessed by means of speech audiometry with open set monosyllables at 40, 55, 70, and 85 dB SPL in quiet with their home MAP. Other psychoacoustic tests were executed depending on the audiologist's clinical judgment. The home MAP and the corresponding test results were entered into FOX. If FOX suggested to make MAP changes, they were implemented and another speech audiometry was performed with the new MAP. FOX suggested MAP changes in 21 subjects (84%). The within-subject comparison showed a significant median improvement of 10, 3, 1, and 7% at 40, 55, 70, and 85 dB SPL, respectively. All but two subjects showed an instantaneous improvement in their mean speech audiometric score. Persons with long-term CI use, who received a FOX-assisted CI fitting at least 6 months ago, display improved speech understanding after MAP modifications, as recommended by the current version of FOX. This can be explained only by intrinsic improvements in FOX's algorithms, as they have resulted from learning. This learning is an inherent feature of artificial intelligence and it may yield measurable benefit in speech understanding even in long-term CI recipients.

  15. Causal judgment from contingency information: a systematic test of the pCI rule.

    White, Peter A

    2004-04-01

    Contingency information is information about the occurrence or nonoccurrence of an effect when a possible cause is present or absent. Under the evidential evaluation model, instances of contingency information are transformed into evidence and causal judgment is based on the proportion of relevant instances evaluated as confirmatory for the candidate cause. In this article, two experiments are reported that were designed to test systematic manipulations of the proportion of confirming instances in relation to other variables: the proportion of instances on which the candidate cause is present, the proportion of instances in which the effect occurs when the cause is present, and the objective contingency. Results showed that both unweighted and weighted versions of the proportion-of-confirmatory-instances rule successfully predicted the main features of the results, with the weighted version proving more successful. Other models, including the power PC theory, failed to predict the results.

    2014-07-01

    Alongside improvements in hearing and communication skills, the rehabilitation of children, adolescents and adults with a cochlear implant (CI) in recent years has increasingly taken into account mental health and quality of life issues. In the context of the programs offered, this study assesses the significance of dance for the mental health of adult clients with a CI. Eleven adult CI users participated in a dance project, which took place as a cooperation between the ENT University Hospital Heidelberg and the Baden State Theatre Karlsruhe. Participants were questioned at two different time points for assessment with the mental health scales (SPG). These scales measure seven different aspects of psychosocial well-being (including autonomy, willpower, affirmation of life and meaningfulness). Significant positive changes in the domains of affirmation of life, self-reflection and social integration were revealed by before and after comparisons; tendencies toward positive change were observed (p ≤ 0.10) in the domains of willpower, naturalness and meaningfulness. No changes were observed in the autonomy domain. The results indicate that the mental health of adult clients with a CI can be strengthened by dance as a complementary rehabilitation module. Concepts of CI rehabilitation should increasingly find anchor in the consideration of such arrangements for its range of offers.

    Full Text Available The Citrus leprosis virus CiLV-C is a quarantine disease of economic importance. Over the past 15 years, this disease has spread to several countries of Central and South America. Colombia has about 45,000 hectares of citrus planted with an annual production of 750,000 tonnes. The CiLV-C has only been detected in the departments of Meta, Casanare and recently Tolima. Meta has 4,300 hectares representing 10% of the national cultivated area, and Casanare, where CiLV-C appeared in 2004, has no more than 500 ha planted with citrus. The presence of the Citrus leprosis virus in Colombia could affect the international market for citrus, other crops and ornamental plants with the United States and other countries without the disease. The false spider mite Brevipalpus phoenicis (Geijskes (Acari: Tenuipalpidae is the main vector of the CiLV-C. Disease management is based on control programs of the vector and diminishing host plants. Chemical mite control is expensive, wasteful and generates resistance to different acaricides. This paper provides basic information on CiLV-C and its vector, advances in diagnosis and methods to control the disease and prevention of its spread

    Full Text Available The article describes critical realism as a philosophical approach that stresses some themes central to all sociological thought: the relation between philosophy and sociology; the notion of cause; the problem of naturalism; the relation between concepts, models, and reality; the relation between agency and structure, and so on. It is further argued that in positing the non-dissolution of the ontological and epistemological dimensions of knowledge, critical realism may represent a viable alternative to the dead-ends of conventionalism and skepticism found in the positivist and pragmatist approaches.

    Apolipoproteins C-I and A-I were radioactively labelled with tritium by (TH)-methyl exchange. The methionine residues were first methylated with (TH)-methyl iodide at pH4 and the reaction products were purified by gel filtration and cation exchange chromatography. The products were then demethylated with 2-mercaptoethanol (6 M) at pH 8.6 to regenerate the apolipoproteins in an unmodified but tritiated form. The specific radioactivity for apolipoprotein C-I and A-I was 3.5 x 10W and 1.5 x 10X dpm/pmol respectively. The properties of (TH)-apolipoprotein C-I were examined by reversed phase HPLC and by incorporation into very low density lipoproteins (VLDL).

    2007-12-01

    Full Text Available A new cirrus detection algorithm for the Spinning Enhanced Visible and Infra-Red Imager (SEVIRI aboard the geostationary Meteosat Second Generation (MSG, MeCiDA, is presented. The algorithm uses the seven infrared channels of SEVIRI and thus provides a consistent scheme for cirrus detection at day and night. MeCiDA combines morphological and multi-spectral threshold tests and detects optically thick and thin ice clouds. The thresholds were determined by a comprehensive theoretical study using radiative transfer simulations for various atmospheric situations as well as by manually evaluating actual satellite observations. The cirrus detection has been optimized for mid- and high latitudes but it could be adapted to other regions as well. The retrieved cirrus masks have been validated by comparison with the Moderate Resolution Imaging Spectroradiometer (MODIS Cirrus Reflection Flag. To study possible seasonal variations in the performance of the algorithm, one scene per month of the year 2004 was randomly selected and compared with the MODIS flag. 81% of the pixels were classified identically by both algorithms. In a comparison of monthly mean values for Europe and the North-Atlantic MeCiDA detected 29.3% cirrus coverage, while the MODIS SWIR cirrus coverage was 38.1%. A lower detection efficiency is to be expected for MeCiDA, as the spatial resolution of MODIS is considerably better and as we used only the thermal infrared channels in contrast to the MODIS algorithm which uses infrared and visible radiances. The advantage of MeCiDA compared to retrievals for polar orbiting instruments or previous geostationary satellites is that it permits the derivation of quantitative data every 15 min, 24 h a day. This high temporal resolution allows the study of diurnal variations and life cycle aspects. MeCiDA is fast enough for near real-time applications.

W większości państw próbuje się temu zaradzić poprzez ustanowienie krajowych standardów usług edukacyjnych oraz redystrybucję środków finansowych, która pozwala zneutralizować wpływ terytorialnych zróżnicowań bazy podatkowej. Niniejsze opracowanie poświęcone będzie analizie skutecznościowych działań w przypadku Polski. W pierwszej części, na podstawie danych panelowych na poziomie gmin, pokazujemy, że mimo różnych instrumentów wyrównawczych stosowanych przez rząd centralny, lokalna baza podatkowa w znaczącym stopniu wpływa na wysokość nakładów przeznaczanych na edukację gimnazjalną. W części drugiej porównujemy liczbę i charakter przedmiotowy godzin lekcyjnych w gimnazjach położonych w najbiedniejszych i najbogatszych gminach. Wedle naszych ustaleń czas nauczania dla uczniów z najbiedniejszych i najbogatszych środowisk nie jest istotnie różny. Nie występują także znaczące różnice wysokości wynagrodzeń nauczycieli. Biedne i bogate gminy różnią się natomiast zakresem indywidualnego wsparcia dla uczniów.

    2017-11-30

    Experimental and modeling studies were completed to explore leveraging physical and chemical fuel properties for improved thermal efficiency of internal combustion engines. Fundamental studies of the ignition chemistry of ethanol and iso-octane blends and constant volume spray chamber studies of gasoline and diesel sprays supported the core research effort which used several reciprocating engine platforms. Single cylinder spark ignition (SI) engine studies were carried out to characterize the impact of ethanol/gasoline, syngas (H2 and CO)/gasoline and other oxygenate/gasoline blends on engine performance. The results of the single-cylinder engine experiments and other data from the literature were used to train a GT Power model and to develop a knock criteria based on reaction chemistry. The models were used to interpret the experimental results and project future performance. Studies were also carried out using a state of the art, direct injection (DI) turbocharged multi- cylinder engine with piezo-actuated fuel injectors to demonstrate the promising spray and spark timing strategies from single-cylinder engine studies on the multi-cylinder engine. Key outcomes and conclusions of the studies were: 1. Efficiency benefits of ethanol and gasoline fuel blends were consistent and substantial (e.g. 5-8% absolute improvement in gross indicated thermal efficiency (GITE)). 2. The best ethanol/gasoline blend (based on maximum thermal efficiency) was determined by the engine hardware and limits based on component protection (e.g. peak in-cylinder pressure or maximum turbocharger inlet temperature) – and not by knock limits. Blends with <50% ethanol delivered significant thermal efficiency gains with conventional SI hardware while maintain good safety integrity to the engine hardware. 3. Other compositions of fuel blends including syngas (H2 and CO) and other dilution strategies provided significant efficiency gains as well (e.g. 5% absolute improvement in ITE). 4. When the

    In a series of earlier papers experimental results on phonon dispersion relations at 80 K in NaCl, KCl, RbCl and RbF have been reported. We now present calculations on these halides using the extended shell model approach with both ions polarizable and including next-nearest neighbour interactions. The parameters obtained in a least squares fit to the experimental points in the symmetry directions have been used to calculate the phonon frequencies in 512,000 equally spaced points in an octant of the Brillouin zone, -whereby, after sorting these into intervals of width {delta}{omega} = 2 x 10{sup 11} rad/sec , the frequency spectrum was obtained. From these spectra the variation of the Debye temperature with temperature was also calculated. The agreement with results from specific heat measurements for NaCl and KCl is quite satisfactory at low temperatures.

    Full Text Available This paper attempts to acquaint Polish readers with the Russian Orthodox philosopher Pavel Florensky’s (1882–1937 thinking on the category of space‑ness, which together with the categories of symbolism and light is one of the key‑words in his theory of aesthetics. The concept of space is, according to Florensky, a criterion for distinguishing art types, although for him it is only a model, which can be used to help form judgments about the world. It is also the basis of being for the artwork itself. Painting and printmaking, among other arts types mentioned by Florensky (poetry, music, theatre, and architecture, have their own particularities in their organization of space. Painting and printmaking are, for Florensky, the truest art forms — art par excellence. The presentation of a threefold interpretation of the category of space‑ness, together with the description and justification of the divisions which are made in art based on these spatial categories by the philosopher is the leitmotiv of this paper. The aim of the paper is to present and discuss the opinions and arguments of the Orthodox thinker from his work Анализ пространственности (и времени в художественно‑изобразительных произведениях, which has not yet been translated into Polish or English.

    Constraint-Induced Movement therapy (CI therapy) is a recognized rehabilitation approach for persons having stroke with mild to moderately severe motor upper extremity deficits. To date, no rehabilitation treatment protocol has been proven effective that addresses both motor performance and spontaneous upper extremity use in the life situation for chronic stroke participants having severe upper extremity impairment with no active finger extension or thumb abduction. This case report describes treatment of a chronic stroke participant with a plegic hand using a CI therapy protocol that combines CI therapy with selected occupational and physical therapy techniques. Treatment consisted of six sessions of adaptive equipment and upper extremity orthotics training followed by a three-week, six-hour daily intervention of CI therapy plus neurodevelopmental treatment. Outcome measures included the Motor Activity Log for very low functioning patients (Grade 5 MAL), upper extremity portion of the Fugl-Meyer Motor Assessment, Graded Wolf Motor Function Test - for very low functioning patients (gWMFT- Grade 5), and Modified Ashworth Scale. The participant showed improvement on each outcome measure with the largest improvement on the Grade 5 MAL. In follow-up, the participant had good retention of his gains in motor performance and use of his more affected arm for real world activities after 3 months; after a one-week brush-up at 3 months, and at one year post-treatment.

    2012-01-01

    The purpose of this study was to examine the musical engagement (participation and attitude) of pediatric CI recipients who were implanted during early childhood and who have reached age 15 or older. A questionnaire was administered to a group of 31 prelingually deaf CI users who receive annual follow up services and assessment in a clinical research center. The questionnaire was used to examine involvement in and attitudes toward music in school, the community, and in the home; social affiliation (hearing, Deaf, both) and mode of communication (oral, manual, both) were also examined. Despite the technical limitations of cochlear implants in transmitting pitch, melody, and tone quality, over two thirds of this sample described music as being important or very important in their lives. A high level of past and present familial involvement in music was associated with higher levels of current involvement and importance of music in the lives of adolescent and young adult CI users. Comparisons were noted with data from prior studies of persons with hearing loss who were non-CI users. PMID:23565029

    2011-06-01

    Full Text Available Os mais recentes esforços de revitalização do enfoque interpretativo na Ciência Política têm sua gênese na década de 1960, quando vários autores passaram a advogar a centralidade do estudo dos significados lingüístico e hermenêutico dos fenômenos políticos. Dentre tais autores, destaca-se o filósofo e politólogo Charles Taylor, cujos textos dos anos 1960 e 1970 desferem críticas contundentes ao naturalismo subjacente ao mainstream da Ciência Política da época. Meu objetivo é explorar a crítica de Taylor ao naturalismo, pensadas no contexto de uma proposta de abordagem interpretativa para a Ciência Política. Primeiramente, contextualizarei as contribuições de Taylor no âmbito mais amplo do interpretive turn nas Ciências Sociais. Em seguida, sumarizarei as reservas que Quentin Skinner e Clifford Geertz apresentam à crítica de Taylor.

    Full text: To evaluate PET/CT in pediatric primary bone tumours (PBT), the accuracy, clinical impact, prognostic indicators in predicting tumour response to therapy and determining epiphyseal involvement were compared to Cl. Methods: A retrospective review of PET/CT scans with CI was performed. Lesions were compared to a reference standard: histopathology or follow up >6 mths. Pt based analysis was performed for clinical impact. Prognostic indicators (SUYmax, tumour size) were compared to histopathology response post chemotherapy. Results: 43 pts (average 12.9 yrs) with osteosarcoma (I 8), Ewing's sarcoma (21), PNE (4) were analysed. 109 PET/CT scans with CI scans were evaluated (371 lesions). 33 lesions were discordant. Accuracy of PET/CT was higher for all lesions than CI (95% vs92%) but sensitivity was lower (79% vs 83%). Excluding lung lesions, sensitivities increased for PET/CT and CI (92% vs 89%). 9pts had PET/CT staging and follow up with histopathological evaluation post chemotherapy: 2pts poor responders, 7 good responders. Good responders had a higher SUYmax at diagnosis compared to poor responders (av 13.84 vs 7.95) but reduced more [10.5(70%) vs 3.5( 45%)]following chemotherapy. There were no false negatives for epiphyseal involvement for PET/CT and CI but one PET/CT was false positive. Conclusion: PET/CT is less sensitive in small lung lesions, but more sensitive in other areas compared to Cl. SUYmax at diagnosis is a poor predictor of response, but percent decrease post therapy was associated with therapeutic response. Change in tumour size on MR is a poor predictor of response. There is improved clinical impact with PET/CT in patient management.

    Full Text Available Este artigo discute as relações entre ciência e arte, principalmente entre física e pintura, com o objetivo de apresentar uma abordagem cultural para a ciência. Dessa forma, entendemos que a compreensão dos conteúdos da ciência torna-se mais significativa. Abordamos diferentes momentos da história desde a revolução científica até o século XX. As relações aqui salientadas não buscam uma relação causal entre ciência e arte, mas sim uma visão mais significativa do que é o processo de construção do conhecimento. Assim, a ciência se desnuda para nós como parte da cultura e pode nos ajudar a compreender melhor o processo histórico que nos trouxe até aqui.With the goal of presenting a cultural approach to science, the article discusses relations between science and art, especially between physics and painting. From this standpoint, we can see how understanding the substance of science becomes more important. Different moments in history are examined, from the scientific revolution down through the twentieth century. The relations highlighted herein are not chosen in an effort to undercover a causal relation between science and art but to arrive at a more meaningful understanding of how knowledge is constructed. Science is thus revealed to be part of culture, which can help us better understand the historical process through which we have come to this point.

    structure has been simplified and the measurement accuracy has increased. Znajomość rozkładu ciśnienia (lub różnicy ciśnień) determinuje opis przepływu płynu przez ośrodek porowaty. W przypadku dużych liczb Reynoldsa nie nastręcza to większych trudności, lecz dla przepływów laminarnych (tj. dla liczb Re (Bear, 1988; Duckworth, 1983; Troskolański, 1957) z zakresu 0.01 do 3) jest to praktycznie niemożliwe w oparciu o dostępne na rynku przyrządy. Przyczyny powodujące taką sytuację zostały omówione w poprzednim opracowaniu (Broda i Filipek, 2012), w którym zwrócono uwagę na trudności pomiarów związane z napięciem powierzchniowym czy włoskowatością (Adamson, 1997). Zaproponowano (Broda i Filipek, 2012) nową, autorską metodę pomiaru bardzo małych różnic ciśnień oraz skonstruowano odpowiednie stanowisko składające się z dwóch oddzielnych zbiorników pomiarowych oraz przeprowadzono pomiary. Z przeprowadzonych badań (Broda i Filipek, 2012) wynikała konieczność zastosowania stabilizacji temperatury urządzenia oraz kompensacji wpływu ciśnienia atmosferycznego na proces pomiarowy. Niniejsza publikacja przedstawia wyniki kontynuacji badań nad metodami i aparaturą do pomiaru bardzo małych różnic ciśnień z uwzględnieniem zdobytych doświadczeń, w oparciu o nowe stanowisko pomiarowe, którego zasadę działania i budowę przedstawiono na rys. 1-5, kolejno przedstawiając koncepcję wykonania pomiaru małych wartości ciśnienia hydrodynamicznego z kompensacją wpływu ciśnienia atmosferycznego rys. 1; ilustrację obrazującą stan odpowiadający przypadkowi braku przepływu płynu przez badany obiekt rys. 2; omawiając stan odpowiadający przypadkowi przepływu płynu przez badany obiekt rys. 3.

    Full Text Available Powikłania neurologiczne w przebiegu niewydolności nerek, zarówno te spowodowane mocznicą, jak i wynikające z jej leczenia, dotyczą ośrodkowego oraz obwodowego układu nerwowego, jak również tkanki mięśniowej i stanowią przyczynę zwiększonej śmiertelności u chorych z niewydolnością nerek. Pacjenci z niewydolnością nerek są szczególnie narażeni na rozwój encefalopatii mocznicowej, encefalopatii nadciśnieniowej, chorób naczyniowych ośrodkowego układu nerwowego bądź zespołów otępiennych. W tej grupie chorych częściej niż w populacji ogólnej rozwijają się mono- i polineuropatie, a choroby nerek należą do częstszych przyczyn zespołu niespokojnych nóg. Pomimo ciągłego postępu terapeutycznego wciąż nie ma skutecznego leczenia wielu tych powikłań, m.in. encefalopatii mocznicowej, miażdżycy, neuropatii czy miopatii. Co więcej, wprowadzenie dializoterapii rozszerzyło spektrum komplikacji o otępienie dializacyjne, krwawienia śródczaszkowe, zespół nierównowagi dializacyjnej, encefalopatię Wernickego i osmotyczną mielinolizę. Leczenie immunosupresyjne stosowane zarówno w chorobach nerek, jak i u chorych po przeszczepie nerki przyczyniło się do rozwoju oportunistycznych infekcji i nowotworzenia w ośrodkowym układzie nerwowym, ponadto niekiedy powikłane jest rozwojem odwracalnej tylnej leukoencefalopatii. Znajomość tych powikłań oraz ścisła współpraca między nefrologami i neurologami mogą przyczynić się do zmniejszenia śmiertelności i poprawy jakości życia chorych z niewydolnością nerek. Należy przy tym pamiętać, że także patologie, które prowadzą do niewydolności nerek (szczególnie choroby układowe tkanki łącznej czy cukrzyca, powodują uszkodzenia ośrodkowego i obwodowego układu nerwowego, a określenie rzeczywistej przyczyny bywa niemożliwe.

    Full Text Available Kamica układu moczowego jest chorobą polegającą na tworzeniu się złogów w drogach moczowych w momencie zaburzenia równowagi pomiędzy promotorami i inhibitorami krystalizacji. Obecnie obserwuje się narastanie częstości występowania kamicy w społeczeństwach krajów wysoko uprzemysłowionych, w tym również w populacji dziecięcej. Problem ten dotyczy nawet 5% tej populacji, a coraz większą grupę stanowią dzieci w okresie niemowlęcym. Wśród metod leczenia wyróżniamy postępowanie zachowawcze lub zabiegowe. Leczeniu zachowawczemu najczęściej poddaje się złogi o średnicy do 5 mm, większe wymagają zastosowania metod inwazyjnych. Wśród metod zabiegowych wyróżniamy metody stosunkowo mało inwazyjne, takie jak: ESWL (kruszenie złogów falą generowaną pozaustrojowo, PCNL (przezskóma nefrolitotrypsja, LTRSL (endoskopowa litotrypsja.

    Seven trace elements ranging from chromium to barium were preconcentrated on Amberlite IR-120 cation exchange paper and determined in an energy dispersive X-ray fluorescence system using a 10 mCi 241 Am source. Sensitivities were experimentally determined and checked with theoretically calculated values. The detection limits are compared with elemental levels present in typical surface waters and those allowed in drinking water. Appropriate conclusions as to feasibility of such a system for environmental monitoring are drawn. (orig.) [de

  8. Emission line relative intensity variations in the symbiotic stars: CI Cygni, BF Cygni, AX Persei and V1016 Cygni

    1982-01-01

    Low resolution spectra (lambda 3800 to lambda 5900) are presented of the symbiotic stars CI Cygni, BF Cygni, AX Persei and V1016 Cygni, which were obtained with the Washburn Observatory Boller and Chivens cassegrain spectrograph and intensified Reticon. The spectra were obtained as part of a monitoring program covering 36 months since November 1978. The nebular electron temperature and density are derived from the [O III] lambda 5007 and lambda 4363 emission lines and the uv intercombination lines of lambda 1661 and lambda 1667. Relative emission line intensity variations were observed in all four stars. The relative emission line changes correlated with photometric minima for CI Cyg, AX Per and possibly BF Cyg. These changes are interpreted as due to a red giant eclipsing a nebula surrounding the exciting source. Based on the [O III] line ratio change, the nebular density of V1016 Cyg has continued to decline since 1978. The thesis also contains a discussion of the use of the emision lines of [Ne III] lambda 3869, [O III] lambda 5007, lambda 4363 and He lambda 5876 to derive nebular electron temperature and density. A decline in the intensity ratios of I(lambda 3869)/(lambda 5007) and I(lambda 5876)/I(lambda 5007) were observed during the 1980 minimum of CI Cyg. The observed I(lambda 3869)/I(lambda 5007) decline was too large to be explained by temperature or density changes. The [Ne III] and He II regions in CI Cyg are therefore closer to the hot source than the more extended (o III] emission region. Contained within the appendix is a discussion of a graphical method of solution ot the nebular temperature and density, which is based on the emission lines of [Ne III], [O III] and He I

  11. Addition by subtraction in coupled-cluster theory: a reconsideration of the CC and CI interface and the nCC hierarchy.

    The nCC hierarchy of coupled-cluster approximations, where n guarantees exactness for n electrons and all products of n electrons are derived and applied to several illustrative problems. The condition of exactness for n=2 defines nCCSD=2CC, with nCCSDT=3CC and nCCSDTQ=4CC being exact for three and four electrons. To achieve this, the minimum number of diagrams is evaluated, which is less than in the corresponding CC model. For all practical purposes, nCC is also the proper definition of a size-extensive CI. 2CC is also an orbitally invariant coupled electron pair approximation. The numerical results of nCC are close to those for the full CC variant, and in some cases are closer to the full CI reference result. As 2CC is exact for separated electron pairs, it is the natural zeroth-order approximation for the correlation problem in molecules with other effects introduced as these units start to interact. The nCC hierarchy of approximations has all the attractive features of CC including its size extensivity, orbital invariance, and orbital insensitivity, but in a conceptually appealing form suited to bond breaking, while being computationally less demanding. Excited states from the equation of motion (EOM-2CC) are also reported, which show results frequently approaching those of EOM-CCSDT.

    Complex interventions are widely used in health systems, public health, education, and communities and are increasingly the subject of systematic reviews. Oversimplification and inconsistencies in reporting about complex interventions can limit the usability of review findings. Although guidance exists to ensure that reports of individual studies and systematic reviews adhere to accepted scientific standards, their design-specific focus leaves important reporting gaps relative to complex interventions in health care. This paper provides a stand-alone extension to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting tool for complex interventions-PRISMA-CI-to help authors, publishers, and readers understand and apply to systematic reviews of complex interventions. PRISMA-CI development followed the Enhancing the QUAlity and Transparency Of health Research Network guidance for extensions and focused on adding or modifying only essential items that are truly unique to complex interventions and are not covered by broader interpretation of current PRISMA guidance. PRISMA-CI provides an important structure and guidance for systematic reviews and meta-analyses for the highly prevalent and dynamic field of complex interventions. Copyright © 2017 The Authors.

    The treatment options for the hyperthyroidism of Graves' disease are antithyroid drugs, surgery and radioiodine, none of which is considered ideal, as they do not act directly on the etiopathogenesis of the disease. Radioiodine has been increasingly used as the treatment of choice because it is a safe and definitive therapy whose administration is very easy. Some authors prefer to administer higher doses in order to deliberately induce hypothyroidism, while others recommend lower doses that result in a lower incidence of hypothyroidism and a greater incidence of euthyroidism. There is no consensus for the optimal regimen of fixed doses to be used and this is the main focus of the present study, where doses of 10 and 15 mCi of 131 I were compared. Among the 164 patients analyzed, 61 (37.2%) were submitted to 10 mCi and 103 (62.8%) to 15 mCi. In the longitudinal analysis it was observed that remission of the hyperthyroidism was statistically different in the sixth month (p 131 I brought about a similar remission of the hyperthyroidism after 12 months of treatment. Moreover, the remission rate of the hyperthyroidism had no association with age, sex or previous therapy with antithyroid drugs. (author)

Prawidłowo dobrana i realizowana metoda szkolenia powinna speł‑ niać funkcję czynnika mobilizującego i wzmacniającego, dzięki któremu pacjent będzie chętniej modyfikował swój styl życia. Głównym celem edukacji dotyczącej diety jest przekazanie i utrwalenie właściwych postaw żywieniowych, przy czym forma przekazu wiedzy na temat odżywiania skierowana do dzieci nie może być taka sama jak przezna‑ czona dla ich rodziców/opiekunów. Związane jest to z różnicami w rozumieniu i przyswajaniu informacji pomiędzy osobami dorosłymi i dziećmi. Mimo to trzeba pamiętać, że rodzina jest społecznością, której członkowie są ze sobą bardzo związani i mają na siebie duży wpływ – nie można zatem pominąć edukacji, która będzie zachęcała całą rodzinę do wspólnych działań. Zmiana nawyków żywieniowych musi dotyczyć wszystkich członków rodziny, gdyż to rodzice poprzez swoje poglądy, preferencje i zachowania kształtują poglądy, preferencje i zachowania dzieci. Również osoba szczupła powinna dostosować się do nowych zasad dla dobra swoich bliskich. Wzajemna moty‑ wacja może być kluczem do sukcesu. Zmiana stylu życia wiąże się też ze zwiększeniem aktywności fizycznej, która jest nieodzownym elementem terapii pacjentów otyłych. Wzrost aktywności ruchowej może skutecznie skrócić czas leczenia oraz przyczynić się do jego lepszych efektów.

The analysis belongs to a branch of linguistics, interpreting language in terms of concepts, viewing it as a source of knowledge about people themselves, different communities, their mentality, ways of perception and interpretations of the way the world is. As a model to present the most thorough understanding of wisdom, the method of cognitive definition proposed by Jerzy Bartmiński is applied. Linguistic-cultural images of wise [person], understood as the concretizations of wisdom have to reveal him/her in opposition to stupid. The cognitive picture of wise is for the most part based on the analysis of features of character and appearance, portrayed behavior, interpersonal relations and the way others have as a perception of wise. Many cognitive parameters of wisdom are revealed while exploring the interactions between people and that of nature (plants, animals which surrounds them and investigating deeper interpersonal relations with other people. The material for research was taken from Polish and Lithuanian proverbs. The latter occur as a result of world perception, everyday life observation, confrontations with its phenomenon. The proverbs are taken from compendiums of Polish and Lithuanian proverbs: Nowa księga przysłów i wyrażeń przysłowiowych (The New Book of Proverbs and Proverbial Phrases by Julian Krzyżanowski and Lietuvių patarlės (Lithuanian Proverbs, Patarlių paralelės (Parallels of Proverbs by Kazys Grigas.

    This study investigated the transition from conventional Compression Ignition (CI) to Partially Premixed Combustion (PPC) in an optical engine for fuels with differing properties. Combustion stratification and emissions were measured with diesel, naphtha and their corresponding surrogate fuels, N-heptane and PRF50. The aim of the study is to link the combustion images with engine out emissions and mixture homogeneity. Single injection strategy with the change of start of injection (SOI) from late to early injections was employed. Results show that combustion phasing trend is similar for diesel/N-heptane as well as for naphtha/PRF50 as the SOI moved from late injection timing to early injection timing. However, there is a significant difference in combustion phasing behavior for gasoline like fuels (naphtha and PRF50) and diesel fuels (diesel and N-heptane). CO emissions show an inverted V-shaped trend with one single peak in the transition zone. A “W” shape trend, with two bottoms at various dilution rates is observed for the UHC emissions. NOX emissions are high in the transition zone and decreased to lower levels in CI and PPC zones. NOX emissions are significantly reduced by reducing the intake O2 concentration with nitrogen. Except for diesel, the other three fuels show lower soot emissions. When compared to diesel like fuels, the natural luminosity of the images are lower for gasoline like fuels, indicating better premixed combustion. As the SOI is changed from CI to PPC mode, the combustion stratification increases towards a peak value in the transition zone and then decreases to a low level in PPC zone. A competition exists between the intake temperature and the dilution rate for the combustion stratification. The level of stratification is higher for real fuels (diesel and naphtha) when compared to surrogate fuel (N-heptane and PRF50).

  10. Naphtha vs. dieseline – The effect of fuel properties on combustion homogeneity in transition from CI combustion towards HCCI

    The scope of this research study pertains to compare the combustion and emission behavior between naphtha and dieseline at different combustion modes. In this study, US dieseline (50% US diesel + 50% RON 91 gasoline) and EU dieseline (45% EU diesel + 55% RON 97 gasoline) with derived cetane number (DCN) of 36 are selected for experimentation in an optical engine. Besides naphtha and dieseline, PRF60 is also tested as a surrogate fuel for naphtha. For the reported fuel with same RON = 60, the effect of physical properties on combustion homogeneity when moving from homogenized charge compression ignition (HCCI) to compression ignition (CI) combustion is studied.The combustion phasing of naphtha at an intake air temperature of 95 °C is taken as the baseline data. The engine experimental results show that higher and lower intake air temperature is required for dieseline mixtures to have same combustion phasing as that of naphtha at HCCI and CI conditions due to the difference in the physical properties. Especially at HCCI mode, due to wider distillation range of dieseline, the evaporation of the fuel is affected so that the gas phase mixture becomes too lean to auto-ignite. However, at partially premixed combustion (PPC) conditions, all test fuels required almost same intake air temperature to match up with the combustion phasing of baseline naphtha. From the rate of heat release and combustion images, it was found that naphtha and PRF60 showed improved premixed combustion when compared dieseline mixtures. The stratification analysis shows that combustion is more stratified for dieseline whereas it is premixed for naphtha and PRF60. The level of stratification linked with soot emission showed that soot concentration is higher at stratified CI combustion whereas near zero soot emissions were noted at PPC mode.

    Full Text Available Objetivo: A medicina pré-moderna tinha por enfoque a harmonia entre o universo e a natureza e tudo era aparentemente possível para os médicos aptos a interpretarem sinais e sintomas. A partir da invenção do estetoscópio inicia-se o processo de investigação do interior dos corpos vivos. Ao longo do tempo, a medicina foi sendo impregnada com a tecnologia e, nos dias atuais, a chamada tecnociência se faz onipresente deixando em segundo plano, ou até mesmo ausente, a interação médico-paciente. Urge a criação de uma nova indústria intelectual com a capacidade de criticar essa nova forma de praticar a medicina embasada principalmente na tecnologia. O objetivo do presente artigo é fazer uma reflexão, por meio da bioética clínica, dessa nova forma de praticar a medicina na tentativa de resgatar o lado humano da ciência médica. Método: Foi realizada uma consulta na base de dados da Medline e LILACS nos últimos dez anos e uma revisão da literatura nacional em torno do tema medicina, bioética, ciência e humanidade. Resultados e conclusão: Nossa conclusão é de a medicina não ser apenas uma ciência, mas também uma arte. Ela exige, em situações particulares, elaborar julgamentos de valor. A Bioética Clínica, surge para guiar caminhos combinando o conhecimento técnico-científico das ciências biomédicas com o conhecimento filosófico. Por meio da Bioética Clínica é possí- vel resgatar os aspectos humanos da arte da medicina

  17. Effect of glycerol ethoxylate as an ignition improver on injection and combustion characteristics of hydrous ethanol under CI engine condition

    International Nuclear Information System (INIS)

    Munsin, R.; Laoonual, Y.; Jugjai, S.; Matsuki, M.; Kosaka, H.

    2015-01-01

    Highlights: • Glycerol ethoxylate (GE) shows the similar results as the commercial additive. • GE decreases injection rate, but increases injection delay and duration of ethanol. • GE shortens ignition delay and decreases heat released in premixed burn of ethanol. • GE has a minor effect on flame temperature of ethanol. • KL factor and soot of ethanol are sensitive to both GE and the commercial additive. - Abstract: This paper investigates the effects of glycerol ethoxylate as an ignition improver on injection and combustion characteristics of hydrous ethanol under a CI engine condition. Injection characteristics were investigated by an in-house injection rate measurement device based on the Zeuch method, while spray combustion has been performed in the rapid compression and expansion machine (RCEM). The CI engine condition indicated as density, pressure and temperature of compressed synthetic gas, consisting of 80% argon and 20% oxygen, at fuel injection timing in RCEM of 21 kg/m 3 , 4.4 MPa and 900 K, respectively. This condition is equivalent to the isentropic compression of air of the actual CI engine with compression ratio of 22. Hydrous ethanol without ignition improver (Eh95) and the ethanol dedicated for heavy duty vehicles (ED95: composed of hydrous ethanol with the commercial additive for ED95) are reference fuels representing low and high quality ethanol fuel for CI engines, respectively. All test fuels are injected at constant heat input. The results indicate that the additional ignition improvers change injection characteristics, i.e. injection delay, injection rate and discharge coefficient of hydrous ethanol. The maximum injection rates at fully opened needle for the ethanol dedicated for heavy duty vehicles (ED95) and hydrous ethanol with 5% glycerol ethoxylate (5%GE) are lower than that of hydrous ethanol without ignition improver (Eh95) by approximately 10%. Additional injection duration is required for ED95 and 5%GE to maintain a

  19. Natural-gas fueled spark-ignition (SI) and compression-ignition (CI) engine performance and emissions

    Energy Technology Data Exchange (ETDEWEB)

    Natural gas is a fossil fuel that has been used and investigated extensively for use in spark-ignition (SI) and compression-ignition (CI) engines. Compared with conventional gasoline engines, SI engines using natural gas can run at higher compression ratios, thus producing higher thermal efficiencies but also increased nitrogen oxide (NO{sub x}) emissions, while producing lower emissions of carbon dioxide (CO{sub 2}), unburned hydrocarbons (HC) and carbon monoxide (CO). These engines also produce relatively less power than gasoline-fueled engines because of the convergence of one or more of three factors: a reduction in volumetric efficiency due to natural-gas injection in the intake manifold; the lower stoichiometric fuel/air ratio of natural gas compared to gasoline; and the lower equivalence ratio at which these engines may be run in order to reduce NO{sub x} emissions. High NO{sub x} emissions, especially at high loads, reduce with exhaust gas recirculation (EGR). However, EGR rates above a maximum value result in misfire and erratic engine operation. Hydrogen gas addition increases this EGR threshold significantly. In addition, hydrogen increases the flame speed of the natural gas-hydrogen mixture. Power levels can be increased with supercharging or turbocharging and intercooling. Natural gas is used to power CI engines via the dual-fuel mode, where a high-cetane fuel is injected along with the natural gas in order to provide a source of ignition for the charge. Thermal efficiency levels compared with normal diesel-fueled CI-engine operation are generally maintained with dual-fuel operation, and smoke levels are reduced significantly. At the same time, lower NO{sub x} and CO{sub 2} emissions, as well as higher HC and CO emissions compared with normal CI-engine operation at low and intermediate loads are recorded. These trends are caused by the low charge temperature and increased ignition delay, resulting in low combustion temperatures. Another factor is

    Pinheiro da Silva, P.; CyberShARE Center of Excellence

    2011-12-01

    Scientists today face the challenge of rethinking the manner in which they document and make available their processes and data in an international cyber-infrastructure of shared resources. Some relevant examples of new scientific practices in the realm of computational and data extraction sciences include: large scale data discovery; data integration; data sharing across distinct scientific domains, systematic management of trust and uncertainty; and comprehensive support for explaining processes and results. This talk introduces CI-Miner - an innovative hands-on, open-source, community-driven methodology to integrate these new scientific practices. It has been developed in collaboration with scientists, with the purpose of capturing, storing and retrieving knowledge about scientific processes and their products, thereby further supporting a new generation of science techniques based on data exploration. CI-Miner uses semantic annotations in the form of W3C Ontology Web Language-based ontologies and Proof Markup Language (PML)-based provenance to represent knowledge. This methodology specializes in general-purpose ontologies, projected into workflow-driven ontologies(WDOs) and into semantic abstract workflows (SAWs). Provenance in PML is CI-Miner's integrative component, which allows scientists to retrieve and reason with the knowledge represented in these new semantic documents. It serves additionally as a platform to share such collected knowledge with the scientific community participating in the international cyber-infrastructure. The integrated semantic documents that are tailored for the use of human epistemic agents may also be utilized by machine epistemic agents, since the documents are based on W3C Resource Description Framework (RDF) notation. This talk is grounded upon interdisciplinary lessons learned through the use of CI-Miner in support of government-funded national and international cyber-infrastructure initiatives in the areas of geo

    Este trabalho foi desenvolvido pelo projeto Astronomia no Recôncavo da Bahia, no Centro de Formação de Professores da Universidade Federal do Recôncavo da Bahia. Traçamos o perfil de um grupo de professores que lecionam conteúdos de Ciências Naturais no recôncavo, alunos do curso de Licenciatura em Ciências Naturais, oferecido dentro do Plano Nacional de Formação de Professores da Educação Básica. Nosso objetivo era avaliar se eles estão preparados para trabalhar conteúdos de Astronomia e identificar suas dificuldades. Os resultados serviram para orientar o professor da disciplina “Terra e Universo”, oferecida no segundo semestre de 2010. Durante a primeira aula da disciplina Terra e Universo, os alunos responderam a um questionário contendo questões abertas e fechadas, divididas em duas partes. A primeira procurando caracterizar profissionalmente os alunos enquanto professores da rede pública da região do Recôncavo Sul da Bahia e uma segunda parte procurando identificar conhecimentos básicos em Astronomia. Os resultados indicam uma predominância de professores do sexo feminino, com idade superior aos 40 anos, pardos e sem formação específica para o ensino de ciências. A maioria leciona há mais de 15 anos para turmas do 1º ao 5º ano, alguns lecionam para turmas de 6º ao 9º ano. Quase todos nunca participaram de um curso de formação continuada em Astronomia. Além disso, não estão habituados a ler revistas especializadas e nem livros com esta temática. Os que procuram ensinar temas voltados para a Astronomia têm, no livro didático, a maior fonte de informação sobre o assunto. As respostas também indicam uma deficiência em conteúdos básicos como a compreensão da esfericidade da Terra, noções de verticalidade e gravidade, incapacidade de identificar a Terra como um planeta, no Sistema Solar, em uma galáxia, no Universo. Estes resultados ressaltam a importância de disciplinas de Astronomia básica na formação dos

    The CI repressor from the temperate bacteriophage TP901-1 consists of two folded domains, an N-terminal helix-turn-helix DNA-binding domain (NTD) and a C-terminal oligomerization domain (CTD), which we here suggest to be further divided into CTD1 and CTD2. Full-length CI is a hexameric protein......, whereas a truncated version, CIΔ58, forms dimers. We identify the dimerization region of CIΔ58 as CTD1 and determine its secondary structure to be helical both within the context of CIΔ58 and in isolation. To our knowledge this is the first time that a helical dimerization domain has been found in a phage...... repressor. We also precisely determine the length of the flexible linker connecting the NTD to the CTD. Using electrophoretic mobility shift assays and native mass spectrometry, we show that CIΔ58 interacts with the O-L operator site as one dimer bound to both half-sites, and with much higher affinity than...

    2008-06-01

    Full Text Available O objetivo deste artigo é discutir a necessidade de repensar o conflito entre disciplinaridade e interdisciplinaridade como se fossem opostos irreconciliáveis. Tentamos demonstrar que a riqueza das ciências humanas cresce através do confronto aberto entre estas duas modalidades de pesquisa, a fim de serem preenchidas as lacunas de ambas. Por meio desta análise, procuramos dar um novo significado para os termos superficialidade e profundidade, tentando superar a antiga oposição que considera profundidade como uma coisa boa em oposição ao caráter superficial. Ao fazermos isto, estamos revendo, com auxílio da teoria de Carlo Ginsburg, a oposição entre retórica e prova, ou, em outros termos, entre factualidade e demonstração argumentativa. Através do enfrentamento dos limites tanto da disciplinaridade quanto da interdisciplinaridade, tentamos apontar novas direções científicas, mostrando soluções marcantes não pelo poder que contêm em si mesmas, mas pela capacidade delas de estimular uma freqüente revisão dos paradigmas das ciências.

    Full Text Available O artigo analisa elementos nucleares no debate nacional e internacional acerca da necessária integração entre ciência, política e práticas em Saúde Coletiva e apresenta subsídios para essa integração. São assinalados alguns obstáculos situados tanto no plano conceitual como aqueles presentes nas relações que se processam em outras esferas e se interpõem à pretendida integração. Dentre os elementos assinalados, evidencia-se que ciência, política e o âmbito das práticas no setor não são campos homogêneos nem tampouco contínuos, implicando relações situadas em diferentes planos e envolvendo diferentes atores. Tais processos desenvolvem-se em arenas distintas, sustentados igualmente por distintas ações, paradigmas e interesses, não isentos de conflitos. Portanto, tal integração é um desafio de grande magnitude, dada sua complexidade e diversidade, objetiva e subjetiva.

    Clara Vasconcelos

    Full Text Available Uma preocupação sempre presente da investigação na área da Psicologia Educacional, é a da compreensão do processo de aprendizagem do aluno, nomeadamente em contexto formal de ensino. Nessa linha, o ensino das ciências recorre a essa área de conhecimento para fundamentar teoricamente concepções e práticas de ensino/aprendizagem, no contexto e ecologia de sala de aula específicos. Neste artigo apresenta-se o contributo das diversas teorias de aprendizagem no processo de ensino/aprendizagem das ciências, especificando a influência de algumas delas nas perspectivas de ensino que foram sendo evolutivamente assumidas. Desse modo, inicia-se uma descrição histórica, referindo perspectivas de ensino apoiadas na vertente behaviorista e termina-se a sua abordagem referindo teorias cognitivo-construtivistas, que deram lugar a perspectivas de ensino voltadas para o papel do aluno, como sujeito ativo na construção do conhecimento, e para o reconhecimento do valor meramente instrumental dos conteúdos curriculares.

    Full Text Available A Bioética surgiu em um momento em que a distância entre a ciência e as humanidades parecia intransponível. Em seu surgimento, a Bioética possuía um apelo para superar essa distância que se revelava fatal para o futuro desenvolvimento da humanidade e para a manutenção das condições de vida nesse planeta. É nesse contexto que V. R. Potter propôs seu conceito original de Bioética como uma integração entre a Biologia e os valores humanos - especialmente a filosofia moral - para orientar a sobrevivência humana. Nesse sentido, o presente texto procurará desenvolver o significado do conceito de Bioética para V. R. Potter e o problema das “duas culturas”, isto é, da necessidade de construção de um diálogo entre as humanidades e a ciência, buscando uma convergência da relação ética de todos os saberes em torno do cuidado da vida.

  15. Identification of operator sites of the CI repressor of phage TP901-1: evolutionary link to other phages

    Johansen, Annette H.; Broendsted, Lone; Hammer, Karin

    2003-01-01

    The repressor encoded by the cI gene of the temperate Lactococcus lactis subsp. cremoris bacteriophage TP901-1 has been purified. Gel-retardation and footprinting analyses identified three palindromic operator sites (O R , O L , and O D ). The operator site O R is located between the two divergent early promoters P R and P L , O L overlaps the transcriptional start of the lytic P L promoter, and O D is located downstream of the mor gene, the first gene in the lytic gene cluster. The function of O L was verified by mutational analysis. Binding was found to be specific and cooperative. Multimeric forms of the repressor were observed, thus indicating that the repressor may bind simultaneously to all three operator sites. Inverted repeats with homology to the operator sites of TP901-1 were identified in phage genomes encoding repressors homologous to CI of TP901-1. Interestingly, the locations of these repeats on the phage genomes correspond to those found in TP901-1, indicating that the same system of cooperative repression of early phage promoters has been inherited by modular evolution

    Optimum cut-off grades determination in mining life affects production planning and ultimate pit limit and it is also important from social, economical and environmental aspects. Calculation of optimum cut-off grades has been less considered for mines containing various mineral processing methods. In this paper, an optimization technique is applied to obtain optimum cut-off grades for both concentration and heap leaching processes. In this technique, production costs and different recoveries of heap leaching method directed into modeling different annual cash flows in copper mines. Considering the governing constraints, the Lagrange multiplier method is practiced to optimize the cut-off grades in which the objective function is supposed to maximize Net Present Value. The results indicate the effect of heap leaching process on the optimum cut-off grades of primary and secondary sulfide deposits. Określanie optymalnego poziomu odcięcia dla zawartości procentowej pierwiastka użytecznego ma poważny wpływ na planowanie produkcji, określanie ostatecznych limitów zasobów złoża; jest to także ważna kwestia z punktu widzenia kwestii społecznych, ekonomicznych i środowiskowych. Obliczanie optymalnego poziomu odcięcia dla zawartości procentowej pierwiastka użytecznego nie było zwykle szeroko rozważane w przypadku kopalni prowadzących ciągły system przeróbki. W pracy tej przedstawiono technikę optymalizacji określania poziomu zawartości procentowej pierwiastka użytecznego z uwzględnieniem zarówno procesów koncentracji jak i ługowania. W metodzie uwzględniono koszty produkcji i różne wskaźniki odzysku rudy, wielkości te wykorzystane zostały do modelowania rocznych przepływów gotówki w kopalniach miedzi. Uwzględniając narzucone ograniczenia, zastosowano metodę mnożników Lagrange'a w celu optymalizacji określania poziomu zawartości procentowej pierwiastka użytecznego, gdzie przyjętą funkcją celu jest maksymalizacja wartości bie

  1. I-Xe dating of aqueous alteration in the CI chondrite Orgueil: I. Magnetite and ferromagnetic separates

    The I-Xe system was studied in a ferromagnetic sample separated from the Orgueil CI carbonaceous chondrite with a hand-held magnet and in two magnetite samples, one chemically separated before and the other one after neutron irradiation. This work was done in order to investigate the effects of chemical separation by LiCl and NaOH on the I-Xe system in magnetite. Our test demonstrated that the chemical separation of magnetite before irradiation using either LiCl or NaOH, or both, does not contaminate the sample with iodine and thus cannot lead to erroneous I-Xe ages due to introduction of uncorrelated 128∗Xe. The I-Xe ages of two Orgueil magnetite samples are mutually consistent within experimental uncertainties and, when normalized to an absolute time scale with the reevaluated Shallowater aubrite standard, place the onset of aqueous alteration on the CI parent body at 4564.3 ± 0.3 Ma, 2.9 ± 0.3 Ma after formation of the CV Ca-AI-rich inclusions (CAIs). The I-Xe age of the ferromagnetic Orgueil separate is 3.4 Ma younger, corresponding to a closure of the I-Xe system at 4560.9 ± 0.2 Ma. These and previously published I-Xe data for Orgueil (Hohenberg et al., 2000) indicate that aqueous alteration on the CI parent body lasted for at least 5 Ma. Although the two magnetite samples gave indistinguishable I-Xe ages, their temperature release profiles differed. One of the two Orgueil magnetites released less radiogenic Xe than the other, 80% of it corresponding to the low-temperature peak of the release profile, compared to only 6% in case of the second Orgueil magnetite sample. This could be due to the difference in iodine trapping efficiencies for magnetite grains of different morphologies. Alternatively, the magnetite grains with the lower radiogenic Xe concentrations may have formed at a later stage of alteration when iodine in an aqueous solution was depleted.

    Full Text Available Przedmiotem rozważań w niniejszym artykule są obecnie obowiązujące zasady sporządzania bilansu przedsiębiorstwa, które straciło zdolność do kontynuacji działalności z powodu postępowania upadłościowego. Bilans likwidacyjny rozpoczyna ostatni cykl życia przedsiębiorstwa – zakończenie jego działalności. W tym okresie zmieniają się cele działalności gospodarczej: jedynym celem staje się sprzedaż jego majątku. Brak zasady kontynuacji działalności przedsiębiorstwa upoważnia, zdaniem autorów, do odstępstw od pewnych zasad rachunkowości, głównie ostrożności, na rzecz zasady treści ekonomicznej. Takie odstępstwo realizuje zapisaną w prawie bilansowym koncepcję true and fair. W artykule postuluje się przyjęcie do wyceny majątku w bilansie likwidacyjnym wartości zbywczej niezależnie od tego, czy jest ona wyższa, czy niższa od jego wartości księgowej.

    The article presents the results of empirical research on the impact of ozone dissolved in fuel-water emulsion on combustion process and concentration of toxic substances in CI engine. The effect of ozone presence in the emulsion and its influence on main engine characteristics (power, torque, fuel consumption) and selected parameters that characterize combustion process (levels of pressures and temperatures in combustion chamber, period of combustion delay, heat release rate, fuel burnt rate) is shown. The change in concentration of toxic components in exhausts gases when engine is fueled with ozonized emulsion was also identified. The empirical research and their analysis showed significant differences in the combustion process when fuel-water emulsion containing ozone was used. These differences include: increased power and efficiency of the engine that are accompanied by reduction in time of combustion delay and beneficial effects of ozone on HC, PM, CO and NOX emissions.

    Full Text Available Racjonalna gospodarka odpadami stanowi jeden z priorytetowych kierunków szeroko rozumianej ochrony środowiska. Fakt umiejętnego zagospodarowania odpadów jest także ważny w kontekście zrównoważonego rozwoju społeczeństw. Do odpadów wyjątkowo uciążliwych dla środowiska zaliczyć należy tworzywa sztuczne. Wzrastające nieustannie ilości tego typu odpadów powodują występowanie problemów zarówno ekologicznych, jak i gospodarczych, co związane jest ze słabą biodegradacją tworzyw. Odpady te zaczęto wykorzystywać do produkcji materiałów budowlanych. Badania nad zagospodarowaniem odpadów z tworzyw sztucznych prowadzone są obecnie w różnych ośrodkach naukowych na świecie. W literaturze można znaleźć opisy wykorzystania odpadów m.in. polietylenu i polipropylenu, styropianu, poliuretanów, poliwęglanu, poliamidu, czy poli(chlorku winylu, jako modyfikatorów betonów i zapraw cementowych. W niniejszym artykule przedstawiono wyniki porównania wybranych właściwości czterech serii zapraw żywicznych zawierających różne odpady tworzyw sztucznych tj.: polipropylen (PP, polietylen (PE, piankę poliuretanową (PU oraz ekspandowany polistyren (EPS. Odpady te pochodziły odpowiednio z kubków po jogurtach, pianki podkładowej pod panele, pianki montażowej oraz płyt styropianowych. Zostały one rozdrobnione i stanowiły częściowy zamiennik kruszywa w zaprawach epoksydowych. Zbadano takie właściwości zapraw, jak: wytrzymałość na zginanie i ściskanie, gęstość objętościowa oraz nasiąkliwość. Wskazano materiał odpadowy, umożliwiający otrzymanie zaprawy cechującej się najkorzystniejszymi wartościami oznaczonych parametrów. Na podstawie uzyskanych wyników badań stwierdzono, że nawet przy 20% substytucji piasku odpadami tworzyw sztucznych, można otrzymać kompozyt charakteryzujący się bardzo dobrymi parametrami wytrzymałościowymi oraz niską nasiąkliwością wodą.

    Only an article rendered by Lia et al. in 2008 has represented charts based on Hoek-Brown criterion for rock slopes, however, these charts are not precise and efficient. Because of this problem, a modification is suggested for the mentioned charts in this study. The new charts are calculated according to four methods. Among the methods, one relates to finite element method using Phase2 software. The other three methods are Janbu, Bishop and Fellenius that belong to limit equilibrium method by using Slide software. For each slope angle, the method having high correlation coefficient is selected as the best one. Then, final charts are rendered according to the selected method and its specific equations. Among forty equations, twenty-five ones or 62.5% relate to numerical method and Phase2 software, six ones or 15% belong to Fellenius limit equilibrium, six ones or 15% relate to Bishop limit equilibrium, and three ones or 7.5% belong to Janbu limit equilibrium. In order to validate new charts, slope stability analysis is carried out for several sections of Chadormalu iron ore open pit mine, Iran. The error percentage of new charts in limit equilibrium method using Slide software and in Bishop method for slopes of Chadormalu iron ore mine are rendered and compared. The charts on a basis of Hoek-Brown failure criterion for rock slopes show less than ±4% error. This indicates that these charts are appropriate tools and their safety factor is optimal for rock slopes. Diagramy stabilności skalistych zboczy otrzymane w oparciu o warunek wytrzymałości Hoeka- Browna znaleźć można jedynie w pracy Lia et al. (2008), choć wykresy te nie są absolutnie dokładne i jasne. Dlatego też w niniejszym artykule zaproponowano pewną modyfikację diagramów. Nowe wykresu sporządzono w oparciu o cztery metody. Jedna z metod opiera się na metodzie elementów skończonych i wykorzystuje oprogramowanie Phase2. Pozostałe trzy podejścia to metody Janbu, Bishopa i Felleniusa bazuj

    Full Text Available O construcionismo social tem sido proposto como um conjunto de elaborações da crise paradigmática que tem sofrido as ciências nas últimas décadas. A complexidade e riqueza de tais elaborações dificultam uma descrição única e consensualmente aceita sobre o construcionismo social. Neste artigo temos como objetivo explorar as propostas de Kenneth J. Gergen e Rom Harré acerca do construcionismo social, seus pressupostos, a visão de ciência promovida por cada uma delas, buscando compreender as implicações para a construção de suas descrições de self. Se é possível identificarmos diversas semelhanças nas propostas destes autores, algumas diferenças significativas marcam a distinção de suas posturas, e servem para mapear o campo de tensões no qual outros autores construcionistas buscam ativamente se posicionar.Social constructionism has been proposed as a set of answers for the scientific paradigmatic crisis of last decades. The complexity and richness of its statements make difficult a unitary and consensual description of what is social constructionism among its proponents. Our objective in this article is to explore in more details Kenneth J. Gergen and Rom Harré's view of social constructionism, its assumptions and view of science, thus favoring an understanding about the way these authors describe and understand the self. Although it is possible to identify many similarities in their proposals, some differences clearly separate their positions, and help to map this field of tensions in which other constructionist authors try to position themselves.

Los análisis de los metales Cd, Zn y Cu en el material en suspensión permitieron determinar que las mayores descargas de estos metales se suceden principalmente desde el Río Magdalena a través del Canal del Clarín y de los ríos que fluyen del piedemonte de la Sierra Nevada de Santa Marta. La comparación de los contenidos en bivalvas permiten determinar la importancia de estos organismos como bioindicadores. Los análisis en las dos especies de peces mostraron una diferenciación en la capacidad de acumulación entre una y otra.  Al comparar los contenidos de metales entre los diferentes tipos de muestras con los cambios en los contenidos en el material en suspensión y la salinidad, se observó que estos dos parámetros son principalmente los que controlan la biodisponibilidad de los metales y además afectan los procesos fisiológicos de los organismos, aumentando o disminuyendo la capacidad de bioacumulación.

    Thermal stability, structure, and magnetic properties of bulk type Ci{sub 88.3}Al{sub 2}Ga{sub 1}P{sub 4.35}B{sub 4.35} alloy in ribbon form have been studied using differential thermal analysis, x-ray diffraction and magnetic measurements. Results reveal that crystallization peak temperature (T{sub x}) and Curie temperature (T{sub c}) of the as-cast alloy are respectively 513 and 370 deg. C. Crystallization of the specimen starts after annealing at 460 deg. C and alpha-Fe is precipitated out. Annealing at temperatures higher than 515 deg. C, produces apart from alpha-Fe, hard magnetic precipitants (Fe{sub 2}B, Fe{sub 3}B), which deteriorate the soft magnetic properties. Lowest coercive field - 9.8 A/m, highest saturation of induction - 1.55 Tesla and best losses - 0.42 W/kg (at 50 Hz and 0.4 kA/m) were obtained for as-cast specimen. Observed good soft magnetic properties of these low cost cast-iron based alloys suggest perspective applications of these soft magnetic alloys as an alternative to the conventional Fe-Si electrical steel and Mn-Zn ferrites.

    1996-01-01

    Objective: Many patients with a diagnosis of pancreatic cancer are not offered any therapeutic intervention other than surgical bypass due to very poor prognosis, poor patient tolerance to current therapeutic regimens, and a dismal tumor response to therapy. In view of these circumstances, an acceptable treatment regimen for pancreatic cancer must first demonstrate an ability to obtain a rapid tumor response with a regimen that will be well tolerated enabling the patient to maintain a good quality of life with full ambulatory status. Materials and Methods: Nine unresectable pancreatic cancer patients ((4(9)) had liver metastases) with an average age of 62 (range: 41-79) were treated with a concurrent regimen consisting of 5-Fluorouracil (CI 200-250 mg/m 2 /24 hrs) and Cisplatin (CI 5mg/24 hrs: 2 weeks on, 1 week off) given simultaneously with 3-D planned BID hyperfractionated radiotherapy to the pancreas (5940 cGy/66 fractions/6.5 weeks), and whole liver (1980 cGy/22 fractions/2 weeks), plus additional dose to the partial liver in metastatic disease. Continuous infusion combination chemotherapy was continued alone after radiotherapy for a total of six months. Chemotherapy was delivered by dual light weight portable external pumps. Hyperalimentation was used as needed to maintain nutritional status and warfarin thromboembolic prophylaxis was also utilized. Tumor response was monitored by monthly abdominal CAT scans, serum markers (CEA, CA 19-9), weight gain, and symptomatology. Full radiographic resolution of tumor mass was considered to be a complete response (CR), whereas 50% or greater radiographic decrease in size was considered a partial response (PR). Evaluation was done by independent diagnostic radiologists. Results: CR and PR of the pancreatic mass was achieved in 88% of all patients ((8(9))). CR was achieved in 44% of all patients ((4(9))). Patients with liver metastases exhibited 75% ((3(4))) PR in liver masses and either CR or PR in the primary site. All

    Full Text Available Chociaż ciąża jest stanem fizjologicznym, to jednak kobiety ciężarne często wymagają diagnostyki i leczenia z powodu poważnych zaburzeń ze strony przewodu pokarmowego. Zwykle są one najczęściej zgłaszanymi dolegliwościami klinicznymi w przebiegu ciąży. U części kobiet pojawiają się zaburzenia specyficzne dla ciąży. Inne ciężarne, z przewlekłymi chorobami przewodu pokarmowego, wymagają specjalnego postępowania w tym okresie. Zrozumienie przebiegu i chorobowości różnorodnych zaburzeń przewodu pokarmowego jest niezbędne, by zoptymalizować opiekę nad tymi pacjentkami. Ciąża ma niewielki wpływ na wydzielanie i wchłanianie, ale wpływa istotnie na motorykę przewodu pokarmowego. Te zaburzenia motoryki są związane z podwyższonym stężeniem żeńskich hormonów płciowych. Dodatkowo powiększająca się macica przemieszcza jelita, co jest przyczyną powszechnych dolegliwości, jakimi są zaparcia. Wiedza na temat mechanizmów adaptacyj‑ nych przewodu pokarmowego w czasie ciąży umożliwia prawidłową interpretację testów laboratoryjnych i badań obrazowych u ciężarnych. Rzadko konieczne jest wykonywanie badań endoskopowych w ciąży. Poten‑ cjalne ryzyko wynikające z endoskopii to niedotlenienie płodu powodowane lekami sedatywnymi oraz ekspo‑ zycja na promieniowanie rentgenowskie. Nie stwierdzono, by badania endoskopowe wywoływały wcześniejsze porody, a obserwacje potwierdzają, że endoskopia w czasie ciąży jest generalnie bezpieczna, przy zachowaniu określonych standardów. Badania powinno się wykonywać w przypadku mocnych wskazań, jeśli to możliwe – w drugim trymestrze ciąży. Procedury najlepiej wykonywać bez sedacji lub z użyciem najmniejszych dawek leków, minimalizując czas ekspozycji na fluoroskopię, optymalnie w obstawie anestezjologicznej i położniczej.

    Recombinant human thyroid-stimulating hormone (rhTSH) enhances {sup 131}I uptake, permitting a decrease in radiation for the treatment of multinodular goiter (MNG). Our objective was to evaluate the safety and efficacy of a single 0.1-mg dose of rhTSH, followed by 30 mCi {sup 131}I, in patients with MNG. Seventeen patients (15 females, 59.0 {+-} 13.1 years), who had never been submitted to {sup 131}I therapy, received a single 0.1-mg injection of rhTSH followed by 30 mCi {sup 131}I on the next day. Mean basal thyroid volume measured by computed tomography was 106.1 {+-} 64.4 mL. {sup 131}I 24-h uptake, TSH, free-T4, T3, thyroglobulin, anti-thyroid antibodies, and thyroid volume were evaluated at regular intervals of 12 months. Mean {sup 131}I 24-h uptake increased from 18.1 {+-} 9.7 to 49.6 {+-} 13.4% (P < 0.001), a median 2.6-fold increase (1.2 to 9.2). Peak hormonal levels were 10.86 {+-} 5.44 mU/L for TSH (a median 15.5-fold increase), 1.80 {+-} 0.48 ng/dL for free-T4, 204.61 {+-} 58.37 ng/dL for T3, and a median of 557.0 ng/mL for thyroglobulin. The adverse effects observed were hyperthyroidism (17.6%), painful thyroiditis (29.4%) and hypothyroidism (52.9%). Thyroid volume was reduced by 34.3 {+-} 14.3% after 6 months (P < 0.001) and by 46.0 {+-} 14.6% after 1 year (P < 0.001). Treatment of MNG with a single 0.1-mg dose of rhTSH, followed by a fixed amount of radioactivity of {sup 131}I, leads to an efficacious decrease in thyroid volume for the majority of the patients, with a moderate incidence of non-serious and readily treatable adverse effects.

Da população de 185 doutores do Doutorado de Ciências Contábeis da FEA/USP, uma amostra de 158 foi selecionada, pois 27 currículos Lattes não estavam disponíveis. Na análise dos dados, utilizou-se estatística descritiva para quantificação da produção científica dos doutores, conforme informações disponíveis nos currículos Lattes. Para análise das redes de pesquisa entre os egressos, utilizou-se o software UNICET®. Os resultados da pesquisa evidenciam as instituições que os egressos estão vinculados atualmente, as funções que exercem nestas instituições, a produção científica dos egressos no período de 1998 a 2008 e as redes de pesquisa predominantes entre os egressos. Constatou-se que a Universidade de São Paulo concentra o maior número de docentes egressos e que a produção científica dos doutores pesquisados está predominantemente publicada em anais de congressos. Quanto às redes, observou-se que estabelecem redes de cooperação com predomínio de ligações fracas em livros, capítulos de livros e textos de revistas/jornais, porém relações de cooperação fortes na publicação de artigos em periódicos. Conclui-se que há ainda necessidade de um fortalecimento nas redes estabelecidas entre os egressos analisados para proporcionar um aprimoramento científico na área contábil.

    Hung, S.C.

    1983-01-01

    Two theoretical studies are used as examples of chemisorption on transition metal surfaces. The first calculation employs the SCF-Sα-SW method to determine the electronic structures of several close-packed Ti-Ti and Ti-H systems. The relative importance of Ti s, p, and electron bonding to its Ti neighbors and to H are reported. The roles of the d electrons in the Ti-Ti and Ti-H bond are discussed. The effect of the presence of an H atom on the first few layers of the metal is also studied. The second set of calculations employs the Hartree-Fock-Roothaan SCF formulation supplemented by configuration-interaction (CI) to determine the energetics of adsorption of an N 2 molecule at a Ti surface. These calculations are made tractable by using a Ti core potential and by a unitary localization transformation to define a local surface region of localized lattice plus adsorbate orbitals. The results show that an underlayer of N atoms forms at the octahedral sites. The calculated adsorption energy of 115 kcal/mole compares favorably with experiment. Binding energy contributions in the several successive steps of the calculations are discussed. Eigenvalue spectra for the selected lattice-adsorbate geometries are compared to the UPS experimental data

    Full Text Available Wzgarda godności y czci pragnienie. A Political Moral Fable from the Archive of Simiaon Polacki Wzgarda godnosci y czci pragnienie is a notable text for its adaptation of a Scriptural source to contemporary problems of political reality in the Polish Commonwealth. The Author considers first the adaptation of passages drawn from the Biblical text and analyses how the poet recasts the short narrative, which was probably of oral origin, into a graceful poetic discourse. In the second part the Author shows how the parable of the Olive, the Fig and the Vine has been adapted to the political situation of the Polish Commonwealth, a Republican system where the King was elected by the nobles. It is better to renounce seeking rank and honors in society – the poet concludes – for the sake of a virtous life and the good of men. In the last part of the paper the problem of authorship of the poem is discussed. In Rolland’s opinion it is possible to ascribe the poem to Simiaon Polacki: both style and ideas expressed in the verses easily find analogies with the other well known literary works of the Bielorusian poet.

External monitoring, whole body counting, urinalysis and fecal analysis were performed to determine the subsequent fate of the contaminant. Five days later, more than 99.5% of the radioactivity was voided in a fecal sample. A single particle, containing 2.85 microCi of /sup 241/AmO2 incorporated in a ceramic matrix, was isolated from the fecal sample. Brief descriptions of the radioanalytical results and dosimetry implications are presented. A shadow shield whole body counter was conveniently used to make an early estimate of the intake. This initial estimate enabled staff to decide that it was not necessary to artifically remove the contaminant. It was estimated that the lower large intestine was the organ which received the highest dose due to the passage of the ceramic particle. Systemic uptake of /sup 241/JAm was indicated by urinalysis. The fractional transfer of /sup 241/Am from the GI tract to the blood was estimated to be less than 6 X 10(-5). This maximum estimate is limited by the MDA of the analytical procedures used. The fractional transfer of the /sup 241/Am from the GI tract to blood in this case is about an order of magnitude less than recent ICRP recommendations for ''all compounds of americium''.

    Full Text Available O artigo tem por objetivo descrever o processo de estruturação do ciclo de estudos sobre as relações raciais no Brasil patrocinado pela Unesco no início dos anos 50. Ao realçar a atuação de determinados atores sociais e suas respectivas visões a respeito do empreendimento a ser realizado no país, foi possível verificar os elos de ligação entre as demandas da agência internacional e o leque de questões formuladas pelas ciências sociais brasileiras. Esta agenda, sintetizada por Arthur Ramos no final dos anos 40, colocava para a inteligência do país inserida no mundo universitário o desafio de associar a qualificação profissional nos campos da Antropologia e da Sociologia e o incremento de pesquisas que pudessem decifrar o que o antropólogo considerava ser a singularidade brasileira, o "laboratório de civilização". Para Arthur Ramos, o tema das relações raciais assumia um lugar privilegiado para a percepção e análise dos desafios da transição do tradicional para o moderno, do cenário de significativas desigualdades sociais e raciais, da diversidade regional e da busca em conformar, em definitivo, uma identidade nacional.
